I bet I can elucidate, Mr. Zhure! Currently, we have 13 active iconics. Even though there are a couple of other iconics in the dungeon (Eberk, Naull) who have no players, I'm going to hold it at 13 for the immediate future. When we played earlier, I was tearing my hair out trying to deal with too many people. As much fun as it would be to run a second game with the other iconics, I just don't have the time.
I will keep track of people who are interested, in case current players have to drop out.
