Sea of Sand Dunes

The Sea of Sand Dunes is an expansive desert located somewhere on Zenith. It has only been featured within the Winx Club Comic Series, where it makes its debut in Issue 90: Adventure on Zenith as the desert that an old hermit by the name of Stylius has made his home.

Desert
As its name would imply, the Sea of Sand Dunes is a vast and empty desert with no notable structures within it. According to King Cryos, the desert is located very far away from Future City and its distance and size are further emphasized by the fact that the Winx need an aircraft just to travel to and search most of it before they ran out of fuel.

Portal into Stylius' Home
Hidden within the desert sands lies a large portal swirling with magic that leads into the home of the hermit, Stylius. The portal's edge is surrounded by a plated border with various symbols written on each tile, while the portal itself appears as a pool of swirling pink energy.

Due to how Stylius prefers being secluded from society, the portal does not lead directly into his home, but rather into a never-ending maze of stairs and corridors.

#90: Adventure on Zenith
After Tecna had been turned into a statue of solid titanium by Tyron's Sentry Robot, the Winx, accompanied by Tecna's robot Byte, head for the Sea of Sand Dunes in the hopes of finding Stylius, Tyron's former mentor, and learning of a way to free Tecna.
