Mothra's Sanctuary

Mothra's Sanctuary formally known as simply The Ballroom of Poseidon was a magical Sanctuary created by the Moth Goddess Motrha from within a former Ballroom section of Poseidon located in back of the ship which connects to that of Poseidon's official Atrium.
It is known to be Mothra's current home on the ship that she shares with her children, and is also the official spot on Poseidon that the Mane 6 would go in order to solve puzzles and summon the Power of Love and Friendship in order to unlock new areas around the Ship at the time of the 2066 Disaster.
Mothra's Sanctuary was known to be the only beautiful spot left on Poseidon after Shadow Rainbow Dash's take over of the ship, hinting that Dark Sparkle's black magic was no match for Mothra's magic, or she never knew of the existence of the Sanctuary at the time of the 2066 Disaster.
