'Wund' is just the name for exiled and disgraced Rekordian nobility, at least in the older days of the setting. It's a long since passed tradition now, though. It's basically like calling someone John/Jane Doe.

On the topic of details like that, I've been considering making a lore topic for optional little bits 'n baubles like that. Not in the OOC just because I don't want to fill up the entire initial post with a bunch of things, so probably in one of the sections of the forum where that sort of thing is allowed, and just link to it in the OOC.
