Sojourn is also a
book by
R.A. Salvatore, it is the third book in the
Dark Elf Trilogy. This is a book about the adventures of
Drizzt Do'Urden, and his first encounters on the surface world.
If you want to start reading books by Salvatore, I would recommend starting with The Crystal Shard, which is the first book from the Icewind Dale Trilogy.
By the way, the Sojourn MUD has gone down forever, much to my dismay. You can visit the web site at www.torilmud.com, it doesn't look like it will ever be back, as Toril, or Sojourn.
