Shards of Dalaya is an emulator for the original EverQuest. In order to play, you need to have EverQuest up through LDoN installed and patched up to date. Then go to www.shardsofdalaya.com and register your account. Its free, and is a great way to play some good old EQ again, back how it was meant to be played before all the ridiculous stuff that happened post PoP. Its set in a different world and there is some custom content and other neat stuff, definitely worth checking out.
