Theikin

Theikin, also called theibeing, is an alterhuman identity that is strongly connected to one's religion, in which otherkin and therian terms do not fully describe the extent of one's identity.

The term was designed to be used hand-in-hand with the label deitykin, but any otherworldly/ethereal kintypes, such as angelkin or demonkin, would work. It was created with polydeism in mind, but one does not need to identify as a polydeist to use the term. One should have a solid religious basis behind their kintype for this identity to work for them.

The term was coined by Discord user veniens.aurora#0780. The flag and symbol were created on the same day.
