Ok so I felt the need to explain this since my Legend of Zelda characters are a made up species and only show up in certain LoZ worlds.

Ok to start off my OCs species are called Valum

Valum are a spirit human like being that lives in abandoned towns, towers, temples, etc. The Valum are a timid group and often don't show themselves to other species; only showing themselves when attacking or becoming hostile. Valum take the topic of death very and I mean very seriously, they help lost souls find their way, mark unmarked graves, protect graveyards and other places related to death, and often have a spirit like companion by their sides. they only become hostile when some one manages to find them and attack them first, destroy graves, or disrespect the dead or temples that are symbolic to death. The Valum are not Native to Hyrule but a three or four live there (even though they don't know where each other are).

The Valum are only in
