Hmmm ... I might be leaning towards a paladin (multiclass cleric?) of the Raven Queen. Because, well, let's face it - making
another avenger would be a little ridiculous. Or perhaps I'll multi into avenger. Who knows, I'm brainstorming. I might make him a full cleric (and possibly multiclass to paladin?) instead, if no one else has a leader they want to play.
Not sure if I would do Str or Cha focus for a paladin yet - it would be nice to see what's in Divine Power, but it looks like that's out of reach for now - or what race. A Str/Wis race would be good if I want to multi to avenger or take ranged cleric powers, but we'll see. Though using a fullblade fluffed as a big scythe would be fantastic (and I know I'm totally stealing that idea from Kamotz, but I've always wanted to play a reaper-esque follower of the death god/goddess

)
Edit: Now, this idea just struck me, but I quite like the idea: A paladin of the Raven Queen, multiclassed dark pact warlock for more deathly dark flavouring. Could go Cha all the way for that combo ... maybe a blue- or black-scaled dragonborn? That could be really fun, assuming someone covers the leader role. If no one else wants to be the leader, though, I would still really enjoy playing the cleric.
