Hey,
I don't know if there is anyone available, but I found some interesting mods in German.

Harluns Wacht Imrpoved 1.1 von AntiHeld http://www.scharesoft.de/joomla/forum/showthread.php?t=36099

Staade Improved 1.0 von AntiHeld http://www.scharesoft.de/joomla/forum/showthread.php?t=36997

Gweden Villa 1.30 von Rotwadron http://www.scharesoft.de/joomla/forum/showthread.php?t=35970

Quell Arkadiens 1.0 von Meister von Cyrodiil http://www.scharesoft.de/joomla/forum/showthread.php?t=36018

I've also seen these four are part of Cyrodil extended, which includes also a fifth mod, already translated by Walkerinshadows, the village by Arielle 1000.

I wonder if anyone german played them and if they are worth searching for someone translating them.

I'm also pretty curious about the Umbra mod by Team kinetic.
