Ahhh, nice. In a bit of a roller coaster, "oh-hey" fashion, very nice. Both Abraxas and Percy developed into quite full characters, and their relationship seeming quite suitable, indeed. Intriguing employment of this marriage act, particularly regarding the tainted/untainted terminology... seems to show quite clearly that invariable tendency to negatively categorize the losing side, and seems quite the way of, eh, handling (or mishandling) the situation, with the inevitable loopholes.
A-and some moste excellent tidbits sprinkled throughout; particularly fond of the following: "Abraxas decided to ask Snape the next time he saw the man about the pros and cons of born versus Transfigured rodents in potions." Because am now all curious. Thank ye. Quite the take on the characters, and a most eenteresting read, all in all. RAD.
