Blood of Dragons is the only author-approved MUSH based on George R.R. Martin's A Song of Ice and Fire. Play the Game of Thrones and become a part of the history of the Seven Kingdoms:
Players who create personal, named NPCs for regular or semi-regular usage need to submit these to the CDB. See +HELP CDB SUBMIT for how to do this.

The Westeros network consists of several different sites, including a forum and a wiki, for all your A Song of Ice and Fire needs.
