Fiction

Cartoon continuity

Daniel and Grimlock entered the corridor and accidentally opened up a secret passageway to an old Quintesson room where exiles were sent to other dimensions. After accidentally stumbling into the room, mainly because of Grimlock, the two ended up in Menonia, again because of Grimlock.

When Blaster, his cassettes, Ultra Magnus, Perceptor and Carly went to find them they discovered the corridor. Rewind had the corridor in his databanks but had no recorded usage of it as it was pre-Autobot. He did manage to translate some of the inscriptions on the walls, one of which detailed the banishment of the Quintesson scientist Al-Badur to a distant, icy world. Madman's Paradise
