A member of The Vanguard, this Shadow Creature is a hero of sorts among the other Shadow Creatures for slaying Izondrial, a Dragonling that apparently possessed a specific power that would've been devastating if unleashed upon The Shadow. The dagger that Izondrial was slayed with later became known as Izondrial's Mercy.
This Shadow Creature's loyalty to Apocrythan is unquestionable. However, this is something that the other Shadow Creatures, especially Kezerix, love to tease her for by claiming that she has a crush on Apocrythan. The Shadow Creatures who tease Yurzara usually end up with their heads being separated from their shoulders, but that only temporarily dissuades any others from trying to tease her.
It should not come as a surprise that Yurzara and Megaloviclus do not get along. At all. Megaloviclus's ambitions of overthrowing Apocrythan do not sit very well with Yurzara, who is constantly suspicious of him. Megaloviclus, for his part, does not appreciate having Yurzara breathing down his neck...EVERY. SINGLE. SECOND.
