D&D 3.0: Tales from Mystara
Holding the eastern banks of the Rugalov, the River Wolves are Goblins that supplement traditional Worgsriding techniques with a small flotilla of war canoes, rafts and one riverboat.
Of the 350 River Wolves, circa one in five is a wolfrider, armed with light lance and a mace or club, while the others fight with short bows and small tridents or short spears.
The River Wolves’ banners show a crudely drawn seal-like animal with a wolf’s head.
Their riverboat counts as a mediocre war machine armed with a single light ram.
The River Wolf chief, Derk Flathead (Goblin 8) commands the riverboat in battle.
Like the Green Raiders, the River Wolves serve the dragon king Argos.
However, they have few shamans of Orcus, and mostly worship Wogar.
