Every time people lament changes to the lore that amount to "not every member of species X is irredeemably evil" and claim the game is removing villains from it, I think how villains of so-caleld evil species fall into two cathegories: a) bland and boring and b)have something else, unrelated to their species going on for them, that makes them interesting.
I’m known for running mostly human campaigns, but one of my favorite tricks is to run a seemingly human villain with personality traits usually associated with an evil monster, then as the adventure goes on the learn that the heraldry features the monster etc etc.
Of course they know me, so they all think it’s metaphor and inspiration.
But at the very last minute, when they think they have him cornered and taken care of all the lackeys…. SURPRISE MOTHERFUCKERS! He drops his magical disguise and it’s an old fashioned D&D lair boss battle!!!!!!!
