Ebon is an eldritch creature.

How can you perceive her? How can I?

When eldritch creatures breed with lesser beings, those beings are that of "half lings"

They are creatures that can have the capability of an elder god, but the aspect in which they can achieve that power is always different, most born being deformed due to the nature of eldritch biology.

Ebon however, has a beak, and with those tentacles she calls a face, uses them to alter sound waves. This allows her to slip by unnoticed, conjure up "effects" that can distract or obscure. Her "wand" or focus point, being that of a string instrument made from a bone of an unknown creature.
