The Forgotten Lands is a massive zone that can be found in the Frontier. The lands are described to be rather flat and appears to be a wasteland that had recently been taken over by life forms. It is the only land-based map area that conceals the location of Frigid Waste (PvP) from other lands of the Frontier.
The Forgotten Lands had experienced some changes during particular updates of the past. It was originally and initially just a grassland with a lack of trees that served little to no interest to many parts of the community. During the introduction of the Otherworld Update where the Otherworld Dimension is colliding against the Frontier's world, there are noteworthy changes, particularly stacks of rocks with trees seen along the pathways of what was once a forgotten, empty land. The Spring Update's arrival further 'enhanced' the landscape of The Forgotten Lands, including more trees than previously before and a forgotten monument serving as the "endgate" of the purchasable Ice Spire home in Matumada.
There are five major landmarks that can be found in specific spots of The Forgotten Lands such as Forgotten Lake a popular fishing spot, Forgotten Monument, Forgotten Rock, Forgotten Woods, and the border between Frigid Waste and The Forgotten Lands the Wooden Spike Border.
Mobs that can be found in the area include Ancient Iron Knight, Blackrock Giant, Blackrock Wolf, Blue Lantern, Blueman, Cellery, Coral Giant, Dark Ghost, Deer, Doll, Forest Walker, Ghost, Green Ghost, Gumbo, Inspector, Lava Munsk, Little Ant, Monstrosity, Mud Genie, Mushroom Head, Otherworldly Knight, Pirate, Purple Ogre, Ratboy, Red Croc Man, Red Lantern, Red Ogre, Tall Bear, Two-Eyed Monstrosity, and the Walker.
Overall, The Forgotten Lands can be very treacherous and dangerous for beginner and mid-game players as these players are nowhere nearby to take shelter or fast-travel, except for the convenient location of Blue Ogre Camp, which is only found on one side of the map area. This map area is not suggested to trespass until the players are properly geared for the dangers that await in the lands.
- The Forgotten Lands is one of the three places where the music does not change from day to night. The other areas being Celestial Field and Frigid Waste (PvP)
- The Forgotten Lands often receive backlash and/or criticism in the past for being nothing more of a barren wasteland of lost opportunities. After the introduction of the Otherworld Update, it slowly gained popularity and less criticism was created due to the abundant number of mobs found in the Frontier.
- It is theorized that The Forgotten Lands is connected to the Otherworld Dimension; being influenced by supernatural energies and/or entities that results in its changes during the Otherworld Update.
