Dark Stephanus

Dark Stephanus is a non-canon character, the evil version of the canonical Stephanus Tavilrond. His female version is Dark Stephania. He only appears in private roleplaying sessions.

Biography
Being a non-canon character - and the evil version of a canon character on top of that - means, that Dark Stephanus never had his own biography or story. It was never defined, if he's the same age as his canon counterpart, or if he's a century older. What is defined, however, is that his personality is different (loyalty and devotion replaced by low cunning, hopeless romanticism replaced by pure lust and desire to possess, desire to protect replaced by petty ambition and lust for power, honour replaced by ruthlessness, etc.), and he is a vampire.

If we assume that he is Stephanus, but from an alternative (non-canon) continuity where he turned to the Dark Side (or was turned into a vampire by Ria Baeni or Héli Calbae), then he was born in the same year as his canon counterpart, but was into a vampire at the age of 19, in 828. Otherwise, it's best to assume that he is at least several decades older than his canon counterpart.
