With all due respect, mighty Grom, what's in it for me?


P.S. "Grom not hit you in head with rock," though compelling, isn't likely to convince the well-helmeted knights of Man.

You'll likely have much more luck with, "Grom give you X dwarven hammers within Y turns. Twofold benefit for Grom: (1) allow Grom to expand, and (2) allow Grom to prove Grom's word honorable, as Man will of course report completion of transaction on internet chat board for whole world to read."
