Intersting and very fitting, introducing the Erastes-Eromenos concept into the magical pureblood society. Your Abraxas is well characterized and works wonderfully for me, and the relationship to Severus, as well as Severus' reactions and actions, follow along very nicely. It's a very unusual Severus we see her, but I can well imagine that in this circumsatances and surroundings, he would show this part of himself. Poppy is one of my favourite characters, and seeing her as Slytherin is a fascinating and pleasant surprise.
