Jacob Grimm
MajorA tall naval captain at 193 centimeters and 108 kilos, with short hair beneath a bloodred watch cap. He wears a black uniform featuring blood stripes, epaulets showing rank, and the name GRIMM on the breast. His build shows strength from years of physical work, occasionally softened by desk duty into slight overweight. When in mess dress, medals cover the white jacket. He carries himself with swagger and often holds a guitar.
Jacob Grimm begins the series as a driven young officer whose physical presence and tactical brilliance quickly earn him command of the destroyer Interceptor. Over successive books his responsibilities expand from solo ship actions to fleet-level operations aboard the battleship BB-17, while his personal life shifts from bachelorhood to marriage with former ONI operative Nadia Grimm. By the time of Grimm’s Legacy he is a decorated captain whose reputation for rescuing royalty, thwarting assassinations, and completing covert missions has made him both a trusted asset of the Alliance president and a marked man among its enemies.
