Any of them in ny'alotha ?
Presumably the Twilight's Hammer have been folded into N'Zoth's conscripted forces and the Maddened Disciples and Acolytes seen in Ny'alotha proper. Curiously, though; there are no mobs tagged "Twilight's Hammer" to be found among them that I've seen.
"We're more of the love, blood, and rhetoric school. Well, we can do you blood and love without the rhetoric, and we can do you blood and rhetoric without the love, and we can do you all three concurrent or consecutive. But we can't give you love and rhetoric without the blood. Blood is compulsory. They're all blood, you see." ― Tom Stoppard, Rosencrantz and Guildenstern are Dead
