From Warhammer - The Old World - Lexicanum
The Grey Lords were the political and historical predecessors of the current Lords of Decay and formed the original Council of Thirteen. In the same fashion as the current council, it was made up by 12 members, augmented by the Horned Rat himself.
Fallen and dead members were replaced by new ambitious candidates. It was possible to challenge an established lord to a ritual duel until death and to replace him, provided one was victorious.
The council was de facto dissolved during the Second Skaven civil war. Some of its surviving members passed the new and deadly test of the Pillar of Commandments and together with new members formed a reorganised Council of Thirteen.
