Sei-Wan in her natural form is an oni, and stands just under ten feet tall. Wearing armor and carrying a two handed blade.

In her polymorphed form, she appears as somewhat human, still retaining some oni features, but in a visage much more palatable to others, and stands around five and a half feet tall.

She decided that it was best to serve Mai Lin, instead of facing an uncertain future after the death of her party in the Frost Giant's complex.
