Aspios, both singular and plural, is the care taker of Serepathy. It is unclear if Aspios is multiple creatures or one creature that can spread itself through multiple bodies. Aspios sees to the maintaing of Serepathy, makes arrangements for those visiting, and acts as a source of information to those that are brought there.
Aspios appears as a humanoid figure in a robe of quicksilver. Those looking inside the hood see no face or head, but instead a glowing glyph that slow turns in the air.
