Probably two to five episodes will be the finale of s1, and s2 will probably start in earnest next year, possibly right before or after SDCC for maximum exposure.
Good. I have already created a head canon for their new characters
Grog's player becomes a extremely stubborn dragonborn paladin- but he's really racist in the sense that he thinks dragonborn are just so much better than all other races and feels the need to protect/intervene in everyone elses affairs because its "the right thing to do"
Vax's player becomes a halfling transmuter wizard who is rather thrifty and materialistic and likes to mess with stuff just to see what happens
Vex's player becomes an assimar monk with a full on bittersweet revenge plot and walks the path of an assasin
Pike's player becomes an elven eldtrich knight who looks for fame and prestidge through cunning and warfare
Percy's player can be a sorcerer, maybe wild magic or something like that; less broody and more bubbly
Kelith's player can be any human nonspell casting class k thx
Scanlan's player can be anything because I'm pretty sure he'd knock it out of the park as a level 1 NPC pesant.
And then they need to find someone else to GM because Matt deserves to play.
And then idk, spelljammer or something.
