I've been pretty busy IRL too, so I feel that. You didn't miss anything important. There was a bit of discussion about whether to implement a numerical game system (I decided a compromise was in order for testing purposes; no specific game rules were implemented yet), and offered some suggestions to people who couldn't decide what character to play. That's about everything you may have missed.
Speaking of character suggestions, I think that's doable. Here's the conditions we have to work with:
- He must have served under Regret the first time around.
- He must have had a powerful lingering regret of his own when he died to become a ghost.
- Something must tie him to Yddrog.
So here's what I'm thinking. Let's say Yddrog captured or killed someone important to him, ideally someone in the current party (to connect him to them), and he regretted being unable to save/avenge them when he died. He thus became a ghost. If his suit of armor was made from Yddrog's dragon scales (so he gets dragon-scale armor! Yass! Gotta find some sick fanart for that), then when Yddrog resurrected, he would be bound to Yddrog's will.
