Description
Neidhart Müller rose to the rank of high admiral in Reinhard von Lohengramm's Galactic Empire. Born in 771 UC (462 IC / 3571 CE), he first appeared as a military attaché at the Imperial embassy on Fezzan around 792 UC (483 IC / 3592 CE), holding the rank of sub-lieutenant. During this assignment, his intelligence work aided in capturing a defecting Imperial noble within Free Planets Alliance territory.

Müller rapidly ascended, becoming one of Reinhard's youngest flag officers by 798 UC (489 IC / 3598 CE). Early in his command, he fought at the Eighth Battle of Iserlohn under Admiral Kempff. When Kempff fell during the defeat, the wounded Müller assumed command of the retreating fleet, swearing vengeance against Yang Wen-li.

His reputation for resilience solidified at the Battle of Vermilion in 799 UC (490 IC / 3599 CE). Arriving just in time to prevent Reinhard's destruction, Müller's fleet engaged Yang Wen-li. His flagship *Lübeck* was destroyed, forcing him to evacuate successively to the *Neustadt*, the *Offenburg*, and finally the *Helten* as each vessel sustained critical damage. Surviving this series of catastrophic losses earned him the moniker "Iron Wall" Müller and an aura of invincibility. For these actions, he received the *Perceval*, the New Galactic Empire's first advanced battleship.

Müller later demonstrated unwavering protective loyalty during the Uruvasi insurrection. Alongside High Admiral Lutz—who sacrificed himself—Müller ensured Reinhard's escape. Though offered a promotion to fleet admiral, he declined, believing Lutz deserved the recognition more, reflecting his principled humility.

In subsequent campaigns, the Müller Fleet became synonymous with defensive excellence and effective rear-guard actions. His forces endured heavy casualties during the assault on Iserlohn Fortress involving Geiersburg. In November 800 UC (491 IC / 3600 CE), during the Reuenthal Rebellion, his fleet formed the final defensive line for the New Imperial Capital, underscoring their trusted role in critical defenses.

Throughout his service, Müller consistently prioritized Reinhard's safety above personal advancement, accepting tactical risks to shield the Kaiser. His command balanced caution with decisive action, while his moral compass emphasized honoring comrades' sacrifices over personal glory.
