In the Dungeons and Dragons World of Greyhawk campaign setting, the Lendore Isles, also known as the Spindrift Isles, are a collection of five large islands in the Solnor Ocean, just off the eastern coast of the former Great Kingdom. This portion of the World of Greyhawk served as the base of Len Lakofka's campaign, and is the setting of the L series of modules authored by Lakofka: L1 The Secret of Bone Hill,L2 The Assassin's Knot, and L3 Deep Dwarven Delve. Lendore Island began the inclusion of material from an author other than Gygax or Rob Kuntz to become incorporated into the Greyhawk setting. Previously unpublished materials from Lakofka's gaming sessions in the late 1970s and early 1980s were released in an article in issue 5 (August 2005) of the Footprints e-zine. Additional material, originally intended for release in L3 Deep Dwarven Delve was released by Lakofka in an article in issue 9 (December 2006) of Footprints. In 2006, Lakofka announced on the Pen & Paper website that he will be releasing L4 and L5 through the Dragonsfoot website, introducing additional material and adventures set in the Lendore Isles. A subsequent threaded discussion on the Dragonsfoot forum gave the title of L4 as "Devilspawn". Both L4 and L5 are now available on Dragonsfoot. L4 is indeed titled "Devilspawn", and includes a second book, "The Lendore Isle Companion". L5 is a three-book set: "The Kroten Campaign Guide", "The Kroten Adventures", and "The Kroten Campaign Companion", plus a separate Map Pack.
In their earliest published form the Lendore Isles are named the Spindrift Isles. The southernmost island was named Lendore Isle after the fictional Suloise Arch Mage who led the human settlement of it. The northern islands are described as being inhabited by elves who hold an isolationist foreign policy. It is notable that the northern islands are described in this source and the one following as being three in number though the map included in the sources show four northern islands. This earliest form is the setting for the L series, which takes place on Lendore Isle. The town of Restenford is detailed in L1 and the town of Garroten (Lake Farmin) in L2.L3 is set in the Restenford/Lake Farmin area but no details are given other than of the dungeon in which the adventure takes place.
