Temporal Tower is where Dialga lives in Pokémon Mystery Dungeon: Explorers of Time & Explorers of Darkness. Dialga is found at the Pinnacle of the tower. He must be fought for the first time as Primal Dialga to place the five Time Gears in five slots to stop the planet's paralysis. He may be fought again to join the team, but not as Primal Dialga. Only the player an the player's partner is allowed to enter Temporal Tower as Lapras will not let any other Pokemon on the player's team including Dialga (if he has been recruited) enter the Hidden Lands.
