Geosenge Underground (XY2)

The Geosenge Underground (Japanese: セキタイ 地下 Sektai Underground) is a post-game only location featured in X2 and Y2. It can not be accessed during the main story due to workers excavating the remains of the elevator. The player first gains access to them when Alexa grants them special permission.
