Gaia Gate
Hub level, Sonic Unleashed
Level theme: ancient ruins
Played as: Sonic the Hedgehog, Sonic the Werehog

Gaia GatesMedia:SonicUnleashed PS2 US manual.pdf, also referred to as Sacred Shrines, serve as the explorable hub areas in the PS2/Wii versions of Sonic Unleashed. Talking to certain townsfolk in each village will earn the player a tablet, granting him or her access to that continent's Gaia Gate. From there, the player can then enter a stage or find items hidden in each room of the Gaia Gate.

Every Gaia Gate has its own theme corresponding to the continent it is in. The gates are all connected and the player can get to another gate by stepping on one of the glowing pads in the room to the left of each gate. Apotos is the only Gaia Gate that doesn't cause Sonic to transform into the Werehog in the main hall, while Eggmanland is the only continent that lacks a Gaia Gate entirely.

Stage Doors

“	The Temple Doors Gaia Gates exist around the world. blocking the way to the temples from all who are unworthy of passing through their doors. Guardians await inside to test the brave.	„
— Secret Document 17 - "The Gaia Gates", PS2/Wii versions of Sonic Unleashed

To access a continent's set of stages (except Eggmanland's), the player must obtain certain tabletsMedia:SonicUnleashed PS2 US manual.pdf to unlock the doors located at the back of the local Gaia Gate. Sun Tablets unlock Day Stages (Sun Doors), Moon Tablets unlock Night Stages (Moon Doors), and Planet Tablets unlock Boss Stages (Planet Doors). Each tablet is associated with a specific Gaia Gate, so they can't be used to access the respective doors in other shrines.

Sun Tablet	Moon Tablet	Planet Tablet

Each continent has a number assigned to it. Apotos and Mazuri are the only zones to share the same continent (First Continent), as they are part of the same planet shard. Apotos is also the only zone that lacks a Planet Door, while Mazuri is the only that lacks both a Sun Door and a Moon Door.

All three tablets are related to the game's storymode. Sun and Moon Tablets are handed to the user by some villagers during the day and the night, respectively. Planet Tablets, however, work differently. You gain a tablet fragment adorned with a red (or blue) jewel as you finish all the day Acts and story-required day missions (respectively, night Acts) of a continent (this excludes Secret Missions and the other optional missions). Once you have the red jewel and blue jewel fragments of the same Planet Tablet, you can ask a specific local villager - one of the Gaia Temple guardians - to assemble it.

Item Doors

“	What Lies Within? The Gaia Gates leading to the temple also hold doors that only open to those who possess Sun and Moon Medals. Behind them lie puzzles with useful prizes!	„
