Kezra

Originally a human, got turned into a demon via blood-incarnation/being in the right place at the right time.

When the world of Nolixuul was cleft in twain by a great dragon, she was separated from her angel lover on the opposite planet.

Through a series of hilarious hijinks, leading an adventuring party around by the nose, and some good old-fashioned murder, she joined both planets up by a portal system just so she could get back to the man she loved.

Red skin, red hair, yellow eyes, yellow wings.
