A Stranger Named Lily

What if Harry ran after Sirius as he fell through the veil? And what if someone pulled him through?

Forced to fight and rescue a weird fish spirit, Harry gets whisked away on an adventure with a kid named Aang, who's apparently the only who can get him home. Oh and there's a war going on. Yay...

Harry/Zuko
