Andros

The realm of Andros (called Tides in the 4Kids Version) is Aisha's home planet. It is a planet that is predominantly covered in water with a few jungled islands, like the Island of Nadu, The Island of Nantros, which contains a volcano, The Island of Guanaco, which also is volcanic and Black Island which is very volcanic.

There are also pirates around these islands. There are also the ruins of buildings above and below the water which were never explained. The current rulers of the realm are King Teredor and Queen Niobe, who are Aisha's parents.

A portal between Tides and the Omega Dimension was built long ago and sealed. Valtor, with the help of the Trix, opened it to escape leaving the portal open. The open portal allowed many criminals to break free of their ice cells in Omega and caused havoc on Tides.

The chaos of the situation would have led to the planet's destruction if Tecna had not sacrificed herself to close the Omega portal from the inside.

There is also a magical link between Tides and the oceans of other planets in the Magical Dimension. In Season 3 Aisha swam into the ocean on Magix to emerge on Tides. According to Aisha and Tressa, the depth of the Ocean of Tides does not reach to and end and does not have a bottom.

A large and dangerous legendary creature called the Kraken lives deep in the oceans of Tides.

This is the world where Valtor's threat began and where it is where it ended when Bloom defeated him in the Omega Portal at end of season 3.

Society
There are two dominant races: mermaids, and the inhabitants of dry land, including fairies, humans and wizards. Both societies are run by a monarchy with the mermaids being clearly matriarchal. The mermaids became monsters when Valtor put a dark spell on them and gained control over them.

The human/fairy/wizard society exists on the surface of the planet. Aisha's family is the predominant royalty, while Nabu is a member of another such family.

Under the sea the Queen of Mermaids is Ligea and her daughter the princess Tressa.

A Merman has never been seen in the series but it does not mean that they do not exist. The merfolk have wings and can fly, as well as live out of the water.

The mermaids have the important task of guarding the portal to the Omega Dimension.

The comic series revealed the fact that Andros has problems with piracy in many parts of the realm. There is even a pirate haven hidden from many.
