Loki Nyx

Turned by Laugar in 1666. They had a brief romantic fling with her, only to later die in a certain massive town fire pretty soon after. Upon awakening and gaining an understanding of the situation, Laugar was nowhere to be seen (probably retreated back into a forest somewhere), so xe pretty much had to figure out the whole vampire thing by hirself. 

They were also the one who taught Helena the ropes of vampirism when she had just turned - also from a fire! They were basically fire buddies back then... and currently, bitter exes.

In the present day, he's kind of super involved with the overall vampire community. Absolutely loves gossip, possibly to a toxic degree. If there's something going on with vampirekind at the moment, she's the one to ask. Xe'll know. They're also one of the biggest reasons Einarr prefers to stay far away from the greater vampire community. :^) 

Though definitely inspired, they have absolutely no relation to the Norse god with the same name. Just someone who named themself after a god. Because of course they would.

Very likely to run a cult.
