Matthias IV, born Matthias von Holswig-Schliestein, was the Emperor of Man from 2434 until 2438 IC. A member of House Holswig-Schliestein, he was the great-grandfather of the current emperor, Karl Franz.[1a][2a]
Matthias IV proved a prudent monarch, though somewhat depressed. His rule came to an end in 2438 IC when he ventured incognito into the streets of Altdorf during a heavy fog in order to learn his subjects' true opinions of him. He never returned, though even today vagrants turn up at the Imperial Palace claiming to be Emperor Matthias.[1a][2a]
