Legends of Norrath
Legends of Norrath (LoN) is an online only collectible card game based on EverQuest and EverQuest II.
LoN is playable from within either of the two games, or via a stand-alone client. Attempting to play LoN from inside EverQuest often crashes EverQuest, however.
LoN has cards which are redeemable for in-game items in EverQuest and EverQuest II.
