Love, Death, and Portals.

An Avatar: The Last Airbender Crossover with Attack on Titan.

Ilah Zhu-Li is a Fire Bender, raised in the Capital of the Fire Nation. Her entire life has been dictated by the powers that be, including her love life. What happens when the Winter Solstice causes her to travel between her world and the next... forcing her to face the difficult decisions she's been running from, and now with a possible, probably definite new love interest?
