Wombo Lombo is a gnome-shaped spellcaster known primarily for Wombo Lombo's Rando-Dungeon. Wombo Lombo is rumored to also have been involved in the construction and/or operation of the “Anniversary Megadungeon.”

Wombo Lombo's Rando-Dungeon was a structure near Barrow's Maw accessible to low-level adventurers. Reports from returning adventurers indicate that the structure and contents of the dungeon changed and evolved with each visiting adventuring party. Unconfirmed rumors indicate that adventuring parties who successfully completed the dungeon have had a hand in designing the layout for future iterations.
