Grakk

Grakk is a half-orc barbarian living in the forest Outside the Enclave. He was originally encountered by a foraging party, which attacked him thinking he was an orc. Grakk was intrigued to meet Humans, knocked some sense into their heads (nonlethally), and started talking with them. He proved his good will by slaughtering an orcish scouting party while the Enclave foraging party watched from hiding.
Grakk speaks mainly Orcish, but knows a little broken Common. He is extremely tough and capable, killing (and sometimes eating) Orcs at every opportunity (he was born an orcish slave). He's willing to trade goods (he mainly has food or hides) or information; however, he roams widely and only encounters Foraging Parties by chance.
