Citlalli's sister Ilhuicatl NEEDED

From Citlalli's Bio:

Citlalli and his sister Ilhuicatl were born under a new moon beneath the stars. They were named Star and Sky because of this. His family bloodline is one from the original cult, so he grew up with descendants from the original cult and has been following Xolotl his whole life.

Citlalli's parents were caught in a flood when he and his sister were 2, and his parents drowned trying to escape. He and his sister wandered the aftermath of the asteroid, killing any who tried to harm them. The two wouldn't take a lot of time to stop and make friends, if someone was a threat they were killed and either sacrificed or eaten if desperate.

Citlalli and Ilhuicatl stumbled upon Atzi through Xolotl, Citl dreamt of the female in a dream and followed his instincts to get there. Both he and his sister joined the pack, even though Ilhuicatl follows Quetzalcoatl more (she won't ever admit to this since Xolotl's original followers are intensly loyal to him).

Ilhuicatl is obedient to her brother, despite not always agreeing with him. She is very intelligent and a very skilled hunter. She is kind and loving. I eventually want her to stand up to her brother if he gets out of hand, reigning him in as needed. I would like her to look similar to Citlalli or look like a wolf that would be named after sky (Like whitish or blackish).
