Adalbert von Fahrenheit was born in 765 UC into an impoverished lesser noble family of the Galactic Empire. He enlisted in the Imperial Fleet, where his natural aptitude for offensive tactics emerged early. During the stagnant Goldenbaum Dynasty, he deliberately suppressed these capabilities to avoid provoking superiors, leading imperial leaders to view him as insubordinate and ineffective. In January 796 UC, he was assigned to Reinhard von Lohengramm's expeditionary force at the Battle of Astarte, becoming the first among his peers to recognize the strategic merit of Reinhard's plan to evade Alliance encirclement. Siegfried Kircheis noted this insight and recommended him to lead the vanguard attack. During the Imperial Civil War in 797 UC, Fahrenheit served as a vice admiral under High Admiral Willibald Joachim von Merkatz within the Lippstadt League opposition forces, standing out as one of the few professionally trained military officers among the predominantly noble leadership. After the League's collapse, he surrendered on Merkatz's counsel and was recruited into Reinhard's fleet, retaining his rank of vice admiral. Under Reinhard's command, he demonstrated unwavering loyalty and rose to high admiral after the establishment of the Goldenlöwe Dynasty. His aggressive tactical style earned him a reputation comparable to Admiral Fritz Joseph Bittenfeld's Black Lancers fleet. Fahrenheit participated in Operation Ragnarök, the invasion of the Free Planets Alliance, and his fleet fought at the Battle of Rantemario but was not deployed at the decisive Battle of Vermillion. In 800 UC, he executed the murderers of João Rebelo, reacting with fury to their attempt to draw parallels to himself. Later that year, during the Battle of the Corridor, Fahrenheit and Bittenfeld were deployed to blockade Yang Wen-li's forces exiting the Iserlohn Corridor. Their fleets became trapped under heavy crossfire near the corridor's exit. To facilitate an imperial retreat, Fahrenheit positioned his flagship, the Asgrimm, at the rear as a defensive shield, enabling numerous imperial ships to escape. He sustained mortal wounds during this defense and, despite the opportunity to evacuate, deliberately remained aboard his crippled vessel, perishing at age 35. He received a posthumous promotion to Fleet Admiral.
