Otfried III
From Gineipaedia, the Legend of Galactic Heroes wiki
Otofried III (Japanese: オトフリート3世) was the 31st kaiser of the Galactic Empire.
History
As crown prince, Otofried III was very popular, and it was assumed he would make a very capable Kaiser. Next to Reinhard von Lohengramm and ___, Otofried III is known to have occupied both the posts of Prime Minister and High Admiral simultaneously. Unfortunately, after Otofried III assumed the throne, a number of conspiracies against the Empire occurred. Most of these conspiracies failed, but they led Kaiser Otofried III to become extremely paranoid. So fearful was he of assassination, he married three different women and changed his heir five times.
It is unknown what happened to his wives after they were divorced, or his sons after they were disowned. It is likely they were either exiled, imprisoned or executed.
Kaiser Otofried III died a lingering death, refusing to consume any food, for fear it might be poisoned.
