That other German poster. Is not Susano. And not Steffen, either, though that has never been claimed in the first place.

Known to be supportive of and nostalgic about the Holy Roman Empire, ideally for him with Prague as capital. Also has a thing about Volapük as a serious international language, which makes even the Esperanto people look down on him.

Translator of the Unholy Roman Empire TL (though it is still stuck in the beginning), and several maps (usually involving some sort of HRE).
