Is there any evidence that Torland (world containing Alefgard) is the same as the lower world in Dragon Quest 6?
Torland is an expanded version of the lower (dark) world that Erdrick went to. Rubiss lives in a shrine that leads deep underwater in Dragon Quest 2 and she lives at the bottom of the sea in her shrine in Dragon Quest 6. The evidence against Torland and the Dragon Quest 6 lower world being the same is there is no landmass that even remotely resembles Alefgard in Dragon Quest 6.
