Abdank

Abdank was a mentally retarded king of Temeria who ruled in the first half of 9th century. It was not easy period - during his "reign" the so-called "Six Years' War" broke out which resulted in the increasing importance of his court mage and advisor Raffard the White, who for fact ruled the country instead of the moron king.

Abdank, who ruled for some time after the killing of Raffard during formation of Brotherhood of Sorcerers, died without a male heir. This resulted in a long though intermittent war of succession between his relatives - dukes of Maribor and Ellander and other participants. These series of conflicts went down in history as the "War of Daggers".
