Newb-flesh here! I'm Steve, and I bring you the even hand of Edgar Bones. He's a very cool guy, so check up on him sometime. His bios pretty complete. I'm hoping to get him dragged into plotty goodness here pretty quick.
If y'all don't know much about Edgar canonically, he becomes one of the Order of the Phoenix so he is likely tied in with you proto-Order types! So he'll be popping up here and there for some friendy bonding stuff.
And of course he is the older brother to one Ms. Amelia Bones. Other than that I've written in that he has an apparent deep respect for one Arthur Weasley, so much that he belays his fancying of Molly Prewett to the 'better man.'
