The Hole

After returning to the mushroom kingdom after the war against The Legion of Blood, the team returns to the Mushroom Kingdom, Hyrule, and Rose remains in the Lylat System. A few months later, the Narrator contacts Toad and Mario, and asks them to help Rose repair a dimensional rift that has opened in the Lylat System. After a brief scene of them repairing the void, Daruk, Luigi and Wendy are called to the flipside to investigate. They receive an encoded message from Mario, but they're unable to decrypt it, at that moment, they're sucked into the rift.

Wendy and Daruk awake within Bowser's castle. A squadron of Gombas happen across them, and throw them into cell block E. Wendy is able to escape, knowing the layout of the prisons. After she frees Daruk, they foolishly head towards Bowser's Chambers.

Elsewhere, Mario, Rose, and Luigi meet the resistance. They first encounter wendy, and 'Blue' or BT-13X as know to the heroes. He explains the predicament, and the status of the resistance. Mario knows of a way to contact the Narrator, but it requires a massive electrical source. There are only two known sources, The Charged Caves, and Bowser's Bastion. Luigi is introduced to 'The Fallen Moons,' Morton, Lemmy, and Ludwig. (All of their X versions)

Daruk and Wendy are surprised to find Black Toad, referred to as 'The Red Iron' in this universe. They enter into battle with him, and are able to eek out a victory. However, they accidentally tip The RI off to the existence of another universe, who then reports this Peach and Bowser. The symbolic and military leader of Bowser's Order.

The Fallen Moons take Luigi to the resistance base, and he reunites with Rose and Mario. Luigi attempts to persuade Blue to take them to the Charged Caves, and he allows it. Ludwig accompanies them there, and they eventually reach the Charged Caves, but The RI and Peach are already there waiting for them.

Daruk and Wendy escape to a bunker that only they and Bowser knew about in the original mushroom kingdom. They find Morton and Lemmy there, surprised to see her once again. She explains their predicament and the four immediately head to the ruins.
