Colonel Boomer is an old elf and a seasoned commander whose blunt authority carries through the chaos of the front. He leads the 106th Bloody Leeches, directing assaults, organizing defenses, and making hard choices about when his troops should advance or withdraw. His command brings him into the wider fight around the castle and guildhall, where he remains a rugged, practical ally to the forces around him.
Description
Boomer is an elderly, grizzled elf, solidly built and stout, with unmistakable pointed ears. His face has the broad, bulldog-like heaviness of a man weathered by a very long life; exact eye, hair, and skin colors are not specified. He commonly wears war gauntlets and keeps an unlit cigar in his mouth, giving his battered military appearance a distinctive finishing touch. He carries himself with the blunt, grounded presence of a veteran commander.
