Akilah

Antagonist

Depends on whose identity she is stealing.

Kilekh are genderless, but Akilah typically presents themself as female.

Thousands of years old

That's complicated

As a Kilekh, she did not have as much access to education as the Guides (Ilekhah). However, she was curious about the world from the time she came into existence. She'd often listen to her father's reports of his scouting missions. Through him, her knowledge of not only her dimension but those seemingly beyond her reach, began to grow. In time, she was considered to be a Kilekhi intellectual.
