So, the 'first" session, scheduled for 1/29, was canceled due to lack of DM attendance.
According to the campaign rules, there is no valid excuse for not attending. If a player can't come, for any reason, he does not get XP. So, logically, if the DM is unable to attend, all the monsters and NPCs should lose XP. Of course, this is rather difficult to implement; it would be easier to give XP to each player that was going to attend instead.
How much experience do we get?
