Undine’s Spring



Undine’s Spring (ウンディーネの泉, Undīne no Izumi), also known as Taboo Spring (禁忌の泉, Kinki no Izumi), is a location in Monster Girl Quest!. It’s the domain of slimes, the home of the Water Spirit Undine and the birthplace of the Heavenly Knight Erubetie.

Description
Despite being called a spring, it stretches for kilometres and it’s one of the few unpolluted areas in Ilias’s world, also being free from human settlement. Due to these factors, slimes congregate here as low-grade slime monsters can only live in unpolluted places with a pure water source.

On the surface, the area is a large serene lake surrounded by plant life. However, setting foot into the lake warps one to a linear subterranean cave system which is where the slime population live.

History
Luka and Alice arrive at the spring so that the former can make a contract with Undine. From within the spring, Erubetie calls out to discourage Luka from entering. He enters regardless.

Through the cave, Luka fights a group of slimes, starting with Jelly Girl, then Blob Girl, then the Green Slime, the Blue Slime, the Red Slime, and the Purple Slime, only to be met by Erubetie after he’s found “invading their home”. Erubetie proceeds to attack Luka and almost kill him, only for Undine to come to his rescue. Erubetie decides to leave and let Undine deal with the human. Undine tests Luka by requesting that he use Sylph and Gnome at the same time. When Luka eventually succeeds, she grants him her power.
