[X] Eh. You changed your mind, you are here to sell that spider carcass!
[X] Ask if either of them would be interested in any future spider corpses you create.
Gold is our bottleneck, this allays it. All three of us want something different from the corpse, and thus all can have it. We dissect it, sell the venom sacs and spinneret to the bottle mage, and the rest of the cadaver to the warrior lady. (who, by the way, looks exceedingly similar to the fighter lady from Heroes of Lesser Earth.)
If we can get a semi-regular buyer for spider corpses, then we have a good way of temporarily boosting our income. Especially once we get some clockworks to help us take them down.
