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:
We’ve now finished adding the batch of houses we created during the summer to the character database. This brings us up to a total of 1767 characters. Of these 13 are Features, 623 are Closed (due to being dead, too young or unable to be in King’s Landing), 171 are Restricted and 960 are Open. So, there ought to be something for everyone in there, or so we hope.
A few more characters will be added later on, but almost all of these will be Features, so the characters currently set to Restricted or Open are pretty much a definitive list of the characters which will be available for players to chose from.
The Westeros network consists of several different sites, including a forum and a wiki, for all your A Song of Ice and Fire needs.
