That's good to hear - an I understand about the momentum going on with only the two (unless Daz is able to return). Yes, the other game is still going, although for the moment they are also down to 2 of 4. [Keia's absence is not yet permanent. Actually, that game is a bit like this one in that they have solidly lost one player and another one hangs in the balance.]
As for merging the two ... I don't know if it would work out well or not. Playerwise I don't think there would be a problem since I do respect all four of you (and Daz and Keia as well). However ... their group has turned into an undead pursuit and one of the characters is a good bit religious type. That would put two strong clerics in the same game without a dedicated fighter. The only arcane support would by Byntrou and Bront's character - and both of those are less than 1/2 time arcanists. It is a valid concept, but I'm not sure the party would be a good mix.
Since you are both seriously enjoying the game and want to see it continue I'll consider this option as well: if either of you have good gaming experience with other players who you know might be interested in a long-term game (I think 15 months qualifies for a long-term game) I can open this up to an invitation only recruitment for a time. I'm not looking to go beyond a party size of 4 (my one failed game was a party of six and it bogged down in waiting for posters on account of the party size). But if you two would like I can open this up to a restricted recruiting. After all, now that the party has successfully discovered the truth about these underground folk and that they aren't interested in antagonistic relations with the party ... there isn't too much left to do before they could find themselves headed toward an inn in search of companions. It would be easy (and fairly quick) to work into the storyline. Thoughts?
However, since you both are agreeable I'll certainly keep it up! I am still enjoying the game. I'll do an IC post promptly. Thanks for your replies!
