[3] In this module, the player characters (PCs) are plummeted into what White Dwarf reviewer Jim Bambra referred to as "a strange partial plane".

Upon landing, the player characters (PCs) find themselves in a surreal, oddly-shaped hallway which contains The Pool of Tears and the entrance to a diminutive garden.

Over the course of the adventure, the PCs run into variations of Lewis Carroll's Wonderland creatures and characters, presented in a Dungeons and Dragons style.

Dungeonland was inspired by Alice's Adventures in Wonderland, and "includes a very dangerous Mad Hatter and March Hare, a deadly game of croquet with the Queen, and a Mock (Dragon) Turtle".

[2] Like its source material, the module is intended to be played in a "light-hearted and zany spirit",[6] though, unlike Carroll's Alice, the player characters repeatedly face potentially lethal combat with monsters.

[2] Dungeonland and The Land Beyond the Magic Mirror were designed to allow the DM to place them as an extension of any existing dungeon intended for 9th–12th level characters.

"[5] In his 1991 book Heroic Worlds, Lawrence Schick said that the scenario was "inspired by Alice and Wonderland, but with the whimsy replaced by opportunities for slaughter".
