From publisher blurb:
House Durbulûk was founded when orcs invaded the empire, and their leader, Yamborgol, murdered the emperor and seized the throne. For three generations he and his kin were the masters of the galaxy. They may have been driven off the throne, but they've survived... as masters of the imperial Mercenary Guild! Fantastically rich and commanding legions of orc mercenaries, they're one of the most powerful houses in the empire. Now, more than ever, they fulfill the motto of their house:
Fly, Fight, Feast!
The House of the Mercenary collects PC options and antagonists for your Starfinder game, compatible with the Starfinder license. Here you'll find:
The orcs of the Empire Arcane, a new setting for Starfinder, and the half-orcs who rule them, descended from Yamborgol and his human empress.
Everything you need to know about this distinctive culture of orcs and half-orcs: their history, technology, magic, culture, and more.
Statistics for two new starships, the Dart-class fighter and the Petard-class assault shuttle, which boards enemy vessels by ramming, clamping on, and melting through the hull!
Detailed information on the Mercenary Guild: how it's organized, how you get in, and how mercenaries are expected to behave in the field (hint: they aren't!).
Orc stat blocks for rookies, veterans, and the half-orc envoys who give the orders, so you have an encounter no matter what level your PCs are at.
