The Dragon Isles
were originally conceptualized during the development of World of Warcraft but were cut early on. They were intended to be located north of Lordaeron and west of Quel'Thalas, as a level 65-70 zone with a raid.[27] They were also planned to host temples to the Old Gods.[28] Some early maps also labeled the isles with the name "Alexstrasza", implying she would be present.[29]
Some working assets labeled "Dragon Isles" are still present in the game files. They were added during the World of Warcraft beta and are used only in a test zone named Designer Island. The set consists of a large nautilus-shaped temple as well as three caves with structures built over the entrances. A hermit crab-shaped temple had also been designed but did not make it to the game files.[28] The nautilus-shaped Old God temple is also present on a piece of concept artwork simply labeled "Dragon Isles" included in both The Art of World of Warcraft[30] and the original in-game credits.
Despite being cut even before the World of Warcraft beta, the small islands still appeared, unlabeled, on the in-game World Map just north of Lordaeron until they were removed in Wrath of the Lich King. It was only in Battle for Azeroth that the first canonical mention of the Dragon Isles was made, before they were finally introduced in Dragonflight.
The concept of red dragons living on islands north of Lordaeron is consistent with the Warcraft II manual stating that dragons are native to "the untamed northlands of Azeroth". The idea of Alexstrasza inhabiting an island near the Eastern Kingdoms was also seen in the canceled Warcraft Adventures: Lord of the Clans, in which she lived in a cave on Crestfall.
Soggoth the Slitherer's remains at the Master's Glaive and the giant kraken temple in the Shrine of the Storm both closely resemble the Dragon Isles temple concept.
