My particular group of monsters barely qualifies as heroes, but boy oh boy do they hate drow.
We're halfway through book 6, First Edition.
Zym, Samsaran Necromancer who is trying to find a way to stop reincarnating. Accompanied by Lavethon, his Magnum Opus, his "familiar" that he crafted by raising the boss of Book 1 as a skeleton and making her into an abomination.
Blight, Homebrew Wyrwood Druid. His "siblings" were kidnapped by drow, and he's going to get them back, no matter how many elves get in his way. Drow or otherwise. Accompanied by Nyx, his Giant Spider animal companion.
Malechai, Human Vampire-Bloodline Sorcerer. Employed by the Demon Lady of Vampires to make sure that whatever the drow are up to fails miserably. Malechai never shuts up, rocks his 8 wisdom like it's going to get him killed, and is absurdly proud of how attractive he is.
Sar'Von, Nagaji Paladin of Desna. Narcoleptic, but fear him when he is awake. He should be the emotional core of the group as a paladin, but the others run circles around him. On a divine quest to save the world from a horror beyond the stars.
And then there's Zyga... Scarred Monk Half Drow. Virtually unkillable, and many have tried. She's a horror movie villain, but as a protagonist. An absolute juggernaut, and a living threat to anything that would get in her way. The leader of our band of miscreants.
