I've put some thought into it, and given how the past few weeks have been extremely busy and taxing for me (feel free to check my posting history; I've barely done anything lately) and that I've not really been keeping up with this game, I think I'm going to bow out while it's quiet and before we're tangled up in this mission. Feel free to use Rykarn as see fit, but if you're looking for a way to write him out without killing him off, just have him decide to stay in London to continue doing what he was doing beforehand.
Sorry guys, it was fun, I just don't feel that my heart was into this for a while and you guys deserve to have a player who's better invested than I am. I hope you all continue to have great adventures together, and maybe I'll see you around down the road.
Take care.
