Maevis

Maevis was a former human turned Infested Amalgamation. and was also Isabel's sister..

Appearance
Maevis looked eerily similar to Isabel. but she had purple eyes instead of the burnt orange eyes that Isabel had.

After being corrupted by the Infested she mutated horrifically. her entire body except for her left eye was covered with infested growth. her body had decayed but had managed to remain "preserved" because of the infestation.
