I've never read Lleu Llaw Gyffes, but this is a wonderful story. Although, Severus is abit too joyous in some places.

According to HBP, Snape's mother's name was Eileen Prince. ('Eileen' fits well in this story, too, though Lydia was all right).

A sweet story, and I liked it a lot.

Pretty awesome story. Different, but I really liked it!
