The Demon Tide of Year 0

Aeternum's recorded history begins with catastrophe. In the year scholars would later call Year 0, a fissure opened in the Shattered Wastes — a barren plateau at the continent's eastern edge — and from it poured the first demon tide. Not scouts, not advance forces. A tide. Tens of thousands of lesser demons followed by things with no names yet recorded, creatures that burned the land simply by touching it.

The human kingdoms of the western coast had never faced anything like it. Their armies were built for war against each other: infantry formations, cavalry charges, the measured violence of civilized conflict. Against demons that regenerated, that didn't fear death, that pressed forward regardless of losses, conventional warfare collapsed within the first season.

By Year 0's winter, three of the seven coastal kingdoms had been erased. Not conquered — erased. No survivors, no tribute negotiations, no terms of surrender. The demon tide consumed what it crossed. The four remaining kingdoms understood: conventional resistance had a deadline, and it was already past.

General Aldric Morvane — The First Blood Knight

Aldric Morvane was the foremost military commander of the Kingdom of Varenheim — the largest of the four surviving kingdoms and the one that bore the greatest share of demon incursions simply by geography. He had spent thirty years defending Varenheim's borders against rival kingdoms and border raiders. He knew how to fight men. He was learning, painfully, how to fight demons.

The histories describe Aldric as pragmatic above all else — a man who evaluated options by their results and not by their aesthetics. When the demon tide advanced to within fifty leagues of Varenheim's capital during Year 0's third season, Aldric convened his officers and told them flatly that they were going to lose unless something fundamental changed. His officers agreed. What he proposed next shocked them into silence.

Aldric had been corresponding, in secret, with Night Queen Seraphel — the oldest known vampire in Aeternum, a creature who had watched civilizations rise and fall from her fortress in the Shadowmere Mountains. She had sent an emissary. She had a proposal. She wanted to make a bargain.

The Terms of Transformation

The terms of the Blood Pact, as it came to be called, were stark and unambiguous. Seraphel offered vampiric transformation to any soldier willing to accept it — the speed, the strength, the healing factor that made a vampire in combat equivalent to a dozen mortal soldiers. In exchange, the transformed would owe no political loyalty to Seraphel, but they would accept the permanent consequences of the change.

What they gave up: mortality, the ability to walk in full daylight without pain, the ability to eat mortal food, and — most devastatingly for some — any hope of normal family life. Children would age and die. Transformed knights would watch everyone they had known grow old and pass while they continued unchanged.

What they gained: power that made the demon tide's most formidable creatures beatable in single combat. Regeneration that healed battlefield wounds between engagements. Speed that rendered conventional demon attack patterns predictable. And immortality — the ability to fight this war and every war after it until Aeternum's end.

Aldric accepted first. He transformed in private, alone with Seraphel's emissary, and spent three days in the agony of conversion. When he emerged, thirty-seven of his most trusted officers were waiting. They had heard what he'd done. All thirty-seven accepted transformation on the same night.

The Battle of Sunken Bridge

The first major engagement with the demon tide following the Blood Knights' transformation came at Sunken Bridge — a centuries-old stone crossing over the Varen River that served as the only viable invasion route for the eastern demon advance. Lose Sunken Bridge and the demon tide reached Varenheim's heartland. Hold it, and the advance stalled.

Previous battles at Sunken Bridge had ended in costly retreats. The demons simply didn't stop. Casualties meant nothing to them. They piled over their own dead to maintain pressure until the defenders exhausted themselves and broke.

The Blood Knights didn't exhaust. For forty hours, Aldric and his thirty-seven held Sunken Bridge against wave attacks that would have shattered any mortal force within the first eight. Aldric's own wound count across the battle was later estimated at sixty-plus individual injuries, each healed fast enough for him to continue fighting. When the dawn of the second day brought a lull in the demon advance, the Blood Knights were still standing. The demons had not crossed.

Word spread across the four kingdoms within days. The Blood Knights had done what entire armies couldn't. The tide could be held. For the first time since Year 0 began, the surviving kingdoms believed they might actually win.

The Corruption Begins

Victory at Sunken Bridge made the Blood Knights celebrated. It also made more transformation requests. Aldric authorized another sixty soldiers to undergo the Blood Pact in the months following, bringing the total to nearly one hundred vampire warriors. The demon tide continued to retreat before them.

The corruption began slowly, and then all at once. The vampiric transformation was not perfectly stable in all individuals. Some adapted seamlessly. Others found the hunger — the need for blood that is the vampire's sustaining requirement — overwhelming. Three Blood Knights in the second cohort of transformations lost control completely during a resupply encampment in Year 2, attacking allied soldiers before being subdued.

More cases followed. Not all Blood Knights were equal. Some could master the hunger indefinitely. Others required strict management — controlled feeding schedules, isolation during high-stress periods. A small number never achieved stable control at all. Aldric, to his lasting grief, personally executed four of his original thirty-seven when their corruption became irreversible.

The corruption cases forced the Blood Knights to develop protocols that would later become the foundation of vampire society's caste system: hierarchies of control, the Blood Vigil initiation ritual designed to identify unstable transformations early, and the law against unauthorized turning that persists to the present day.

Formation of the Crimson Empire

By Year 15, the demon tide had been driven back to the Shattered Wastes. The fissure that birthed it had sealed — not permanently, scholars would later learn, but sealed enough. The immediate crisis was over. The Blood Knights, now numbering in the hundreds through carefully managed expansion, found themselves in a world that had changed around them.

The four surviving kingdoms were exhausted, depopulated, and economically ruined by fifteen years of existential war. The political structures that had defined pre-Year-0 Aeternum no longer meaningfully existed. Power had shifted to whoever could provide security — and only the Blood Knights could guarantee that.

Aldric Morvane, still alive and still commanding at Year 15, made a deliberate choice: consolidate rather than fragment. The four kingdoms were formally dissolved and merged into a single polity under Blood Knight governance. The Crimson Empire was declared in Year 16. Aldric served as its first Lord-Protector. Night Queen Seraphel, notably, declined the offer of any formal role — she had what she wanted from the Blood Pact, and political administration held no interest for her.

The Blood Knights became the empire's ruling class not through conquest but through consensus. The mortal populations of Aeternum had watched them bleed for fifteen years. Whatever else vampires were, they had earned the authority they held.

Legacy in Modern Aeternum

The Crimson Empire's specific political form has changed many times over the centuries since Year 16. It fragmented, reformed, merged with the Blood Covenant during the Consolidation Wars, and exists today in a looser configuration that most modern Aeternians simply call vampire-held territory. But the Blood Knights' institutional legacy has never faded.

Every vampire turning in Aeternum still follows the Blood Vigil ritual established to identify unstable transformations. Every vampire settlement still observes the anti-unauthorized-turning law that Aldric codified. The hunger management protocols developed during the Blood Knights' early years are taught to every new vampire as fundamental survival knowledge.

Most significantly, the philosophical identity of the vampire faction in modern Aeternum — the idea that power carries obligation, that the strong exist to protect rather than simply dominate, that restraint in applying strength is a virtue rather than a weakness — traces directly to Aldric's leadership style and the example he set over his first century of command.

Game Connection

The Dark Knight subclass is the direct mechanical descendant of the original Blood Knights. The subclass description in the game's lore text explicitly names Aldric Morvane as the lineage founder, and the Dark Knight's core passive — Shadow Armor — is described as a refined version of the defensive technique Aldric developed for fighting in daylight-adjacent conditions where vampiric speed was partially suppressed.

The Shadow Form vampire race passive also traces its origin to Blood Knight combat techniques. The ability to enter a semi-incorporeal state for brief periods was a Blood Knight survival adaptation, recorded in Aldric's own tactical journals and later systematized into the race passive that all vampires carry.

When you play a Dark Knight in Vampires vs. Werewolves, you're not just running a tank build. You're continuing a military lineage that is, by Aeternum's reckoning, the reason the continent still exists.

"Even today, newly turned vampires in Aeternum undergo a ritual called the Blood Vigil — a recreation of Aldric's first night as an immortal. Old customs die hard. Old soldiers die harder."
