These are the daimonin pages of Cher and his friends. Daimonin is a MMORPG. You can read more about Daimonin at ↗http://www.daimonin.net/.
The SVN migration sandbox snapshots are no longer available.
Gridarta is a project of its own. Cher's Gridarta pages are at ↗http://www.riedquat.de/projects/gridarta/. The official Gridarta website is at ↗http://gridarta.sourceforge.net/.
The map maker package here was hopelessly outdated. I've therefore decided to remove it. You can obtain the latest map maker package and Gridarta for Daimonin release from the ↗Download Page at the Daimonin Website.
