Ygg: Words of Power
Half-Orcs and Orcs constitute a race of Jotun who, unlike the rest of their kind, dwell primarily in Midgard. They are diminutive by the standards of other Giant-kin but they stand a full head or more taller than Humans and are more robust than most other races. Orcs are descendents of a tribe of Jotuns called the Drythne who sold their allegience to the goddess Hel, and murdered, plundered, and raped a path across Midgard in mad crusade. Orcs live a tribal existence in Midgard and are often shunned by Humans and other races for their relation to other Giants.
Orcs, Half-Orcs, and Orogs are racially indistinct in Ygg, but PCs wishing to play one of them should use Half-Orcs from the Player’s Handbook 2.
