Gemini

This is the composite version of Illy and Tam.

Illamar and Tamris, the twin daughters of Elphembre the Red, who is the son of Erik Ironbender (Elphembre has a younger twin sister named Petra). They're from ~lex-n-karu's Fateverse (specifically the Gemini arc, which starts with The Amazon).

They are rarely allowed out of the house, and only in their father’s company. As a result, Tam suffers from chronic depression and Illy accidentally created a boyfriend to keep her company.
