Aliasing zherlthsh/zealotus -> zealotus/zherlthsh.
Reason: Either of zherlthsh to zealotus or zealotus to zherlthsh.
The reason being that they're variations of the same name for the same monster/character from Ragnarok Online. Zherlthsh is the official translation from the Korean, and how the name appears in english in the game. Zealotus, however, is the generally accepted translation among the fandom. It's also easier to remember and spell.
