It's easy to spot giff in a room: these burly folk are 7-foot-tall, hippopotamus-headed people. In Wildspace and the associated ports, giff are most often encountered as spacefaring mercenaries. These troops are renowned for their martial training and love of explosives and are typically armed with gleaming pistols and muskets. The stat block here represents one of those mercenaries.
Every aspect of these spacefaring giff's society is organized along military lines. From birth until death, each has a military rank. Promotions don't depend on age but are granted by a superior as a reward for valor.
Muskets and grenades are the specialties of many giff regiments. The bigger the boom, the brighter the flash, and the thicker the smoke it produces, the greater the glory for the one wielding the weapon. Giff mercenaries have been known to accept payment in kegs of gunpowder in preference to gold, gems, or other currency.
Giff are split into two camps concerning how their name is pronounced. Half of them say it with a hard g, half with a soft g. Disagreements over the correct pronunciation often blossom into hard feelings, loud arguments, and head-butting contests, but they rarely escalate beyond that.
