Hamish was a halfling rogue who specialized in scouting and spying skills. He was remarkably strong for a halfling, and also reasonably charismatic. Though he primarily concentrated on improving his scouting skills, he also had some ability as a sorcerer.
As a young halfling, he had been captured and imprisoned by orcs for a significant length of time. His father had left the Enclave under unclear circumstances some time before, which was extremely unusual then.
He went on several exploration missions outside the Enclave in the company of a few other adventurers, including Grubwar's ill-fated sojourn. Among other things, he engaged in spying on orcish activities and relayed that information back to the Enclave. Hamish and his party explored a few days' travel away from the Enclave in several directions.
