Relix

Relix (also called Realix) is a realm introduced in Season 2.

Overview
Relix holds the Ultimate Power which is contained in the Crystal of Power. Relix seems to consist of mostly void, with ruins of an ancient stone building floating in it and stones floating around these ruins. The sky of Relix is a red-gray color.

Codex Portal
In order to open the portal to Relix, both the powers of light and darkness must come together and combine the four fragments of the Codex. Once in Realix, in order to obtain the Ultimate Power contained within the Crystal of Power, the two forces must perform a ritual to summon the crystal.

Copied Codex Portal
A portal to Relix can be opened with the copied pieces of the Codex. Once activated, one must solve a puzzle in order to go beyond the gate.

Season 2
With the help of the Guardian Pixies who, having a copy of the Codex, were able to open another portal to the Relix, the Winx, the Specialists and the teachers and headmasters of the three schools (Alfea, Red Fountain and Cloud Tower) went to the Relix Realm to rescue Bloom and the Trix went there to take revenge from Darkar for having betrayed them. Sky helps Bloom become herself again by revealing his feelings for her and the Winx defeated Darkar by using a Charmix Convergence. After that the Realm of Relix was sealed for good, since there were no longer any Codex to go there, and the Trix remained imprisoned there after the final battle with Darkar for some weeks till they were captured by the security services of Magix, frozen and sent to the Omega Dimension.

The Shadow Phoenix
The Guardian Pixies were capable of opening the portal, allowing the Winx to enter and try to stop Bloom from completing the spell. Unfortunately, they could not and the ultimate power was summoned. Darkar proceeds to absorb it but with just one chance, Sky confesses his love for Bloom and was able to bring her back to normal. She relinquishes the ultimate power from Darkar. The Winx then finish Darkar off by doing a Charmix Convergence. The realm begins to collapse and so the Winx, Specialists, Pixies, and their teachers escape.

Season 2
In "Winx Club: Join the Club," in Relix, the Winx battle Darkar in his phoenix form and destroy him once and for all.

Trivia

 * The name of the Relix comes from the word Relic, which is the name of what remains after something has been through partial destruction or decay.
 * It his unknown how the authorities of Magix were able to enter the Relix to capture the Trix and send them to the Omega Dimension. It may be possible that the Knights of the Fortress of Light were able to enter the Relix and capture the Trix, since they possess very advanced magic and are responsible for punishing the criminals of the Magic Dimension.
