Spell: Call of the Shadowy Void (a Sept-umbra creation) (Patreon)

A hole appears, so deep you see only darkness at the bottom...and you feel the sudden urge to jump into it.

This spell idea began with the idea of just a "black hole" of some sort, which turned into conjuring a hole that is dark at the bottom, and then I thought of adding a magical bit of high places phenomenon.

This is my creation for day 18 of Sept-umbra.
