OK, so now we have an even bigger problem than player inactivity.
We started with six players. Eiki-mun left early on, Madman's character has been sidelined (apparently as a deliberate action on his part), and now Witchyjoshy has left for unknown reasons (of which I was only informed by a PM from Cerim Treascair). I have tentatively asked Madman to play Caladur until Witchyjoshy returns.
The campaign was designed for at least four characters, and we're now left with three. Continuing on this basis is difficult enough as it is, and I cannot be sure that someone else won't suddenly decide to leave in the next few weeks. Remember, I'm only DMing because nobody else was able to do it.
I'm going to have to ask now whether we want to continue the game, and I will need at least four responses from people wanting to play before I can do so.
