God, it's been a long time since I've read this story... but it was an amazing fan-fiction that I found on FF.net back in 2005-ish? That sounds about right.

It had something to do with Tenshi, and it was with Kagome staying with Sesshomaru in his castle, and they had the lords and ladies of the other lands visit, and at the end of the story Kagome and Sesshomaru were in this land of ice and snow... I want to say something about Wings and Tenshi sounds right, and I found a story called Wings of Tenshi, but that's not it.

It had a lot of chapters and I am just struggling to remember what it was!

If anyone has an idea, please let me know! I've been looking for this story for forever! Thank you!
