Oblivion (Winx Club)
It is a dimension that serves as a prison for worse criminals than those of in the Omega Dimension. It also has the power to confuse anyone with false visions as they stay inside their cells that look like cubes. It has a powerful magic that even any powerful convergence magic cannot stabilize its portal. There is an entrance that can be summoned as an ocean gate in Andros. There is also another way to enter it - through a powerful dark spell that requires a young ruler to create a portal to it.
