Radiation Gate

The Radiation Gate is one of the two primary gates controlling the Planet Storm on Auldrant. It is supposedly located in Auldrant's south pole and serves as the exit point for memory particles of the Seventh Fonon. The Radiation Gate is located in a deep, rugged chasm containing several fossilized bones of monsters. At the bottom of the gate is the passage ring for the second Sephiroth and the fonic glyph that keeps the gate operating.

History
The gate was supposedly built during the Dawn Age. Not much is known of the gate's history except that it starts off the Planetary Storm.

During the events of Tales of the Abyss, Luke's party first intended to go to the Radiation Gate to control the Sephiroth for the safe descent of the Outer Lands. However due to Van's actions in the Absorption Gate, Jade states that there is not enough time to do so. To compensate, Asch heads to the Radiation Gate so that he and Luke can sumitaniously control both of the Sephiroth at once.

Luke's party however first visits the Radiation Gate in a attempt to deactivate Eldrant's barrier. Thanks to Noelle's piloting skills, they managed to escape the fonon barrage and safetly land in the gate. At the bottom, they confront Mohs who is on the brink of loosing his intelligence due to the effects of the rejected Seventh Fonons. They successfully kill him and deactivate the fonic glyph operating the gate. With the deactivation of both gates, the party prepares for the infiltration of Eldrant.
