The State Defence Legion is an armed paramilitary made up of Castlefigs loyal to regional leader and representative of the central Legoland government, Lord Colossus Denarius. The militia was raised by Lord Colossus Denarius in October 2009 to help counter the growing threat to his administration.

Rarely participating in combined operations with the LRG, the State Defence Legion focuses on retaining control of Castleland’s key urban settlements and power bases.

It is widely believed that many generals in the LRG consider the SDL a rag-tag bunch of indisciplined cowardly bandits and no match for either the Legoban or Al-Kyeda fighters.
