Wow, aren't you creative? I loved the Founders lore, and how Severus was brought back in what is perhaps the creative way I've seen yet. This is my first time reading AS/S, and so I think you for making it an enjoyable one.
The ending made me so very happy. I only like fluff when it's Snarry (a few exceptions), and it made me very giddy indeed.
Fabulous job on great writing and creativity. A++++
