Initial concept wise I'd say I'm looking at a Dragonborn Paladin. Pretty cliche for a dragon themed/involving campaign, but they happen to be a favorite of mine. Alternatively, probably an elf of some flavor.<br/><br/>If I recall correctly, 5e Paladins are flexible enough in mechanical possibility that this doesn't lay claim to (or shoehorn me into) being a defensive specialist party member. At least, I remember my unorthodoxly built offensive focused Paladin working during that near release oneshot game I mentioned. So this doesn't lock anyone wanting the role out of it.<br/><br/>I also recall 5e not having the lawful good requirement. Which combined with the Oaths of Vengeance, Conquest, and Treachery (the latter two being some playtest level stuff released last month apparently) makes being a Tiamat aligned paladin for the event the game is in the cult instead of stopping it a reasonable possibility.<br/><br/>EDIT: So many posts I didn't see. This was written before I'd seen anyone else posting any ideas of their own.
