...is each other.
A couple of my original characters, Rasputin and Satire. Rasputin is Voidborn, no parents, no family aside from his twin sister (who i will draw a separate pic for) and Satire, the shadowfiend bound to him.
They have a very love-hate relationship, as they're tied together down to the most intimate of connections, despite being quite different in personality. Rasputin is calm and gentle, while Satire is chaotic and prone to cruelty.
And Satire's face is covered by an expressive mask that shifts to match his mood. Most of the time it wears a crazy grin on it, like in the image.
