Meet Icknox, a Nurgle lord of Chaos with a plasma pistol, a power fist (that hideously over-sized hand), and a palanquin. Even though I try to play dedicated Slaanesh, there's always something oddly satisfying about making Nurglite models.
The armor plating and the throne he sits on comes from a Cave Troll kit from LoTR, the 'power fist' is an arm from a GW River Trolls kit, the lion's share of the minions carrying the palanquin are Rot Puppets from... Maximini, I think? The rest is a mix of various CSM parts and nurglings.
