- Part of a mountain range running from the northwest of Sylvana to the southeast. Fierce snowstorms are common in the northwest.
Mt. Roneal is a snowy mountain range in Tales of the Abyss.
Mt. Roneal is located on Sylvana, northwest of Keterburg. People rarely approach the area due to powerful monsters that live within its caves, and also due to the threat of avalanches caused by too much noise. It is home to a Sephiroth Tree.
Prior to the events of the story, in N.D. 1991, Gelda Nebilim failed a planetary arte experiment at Mt. Roneal, resulting in the deaths of many Oracle Knights. Nine years later, Field Marshal McGovern, Sr. battled the culprit of the "serial fonist killings", the replicated Nebilim herself, and sealed her within Mt. Roneal in a classified area known as Nebilim's Crag. At some point, the God-Generals were gravely injured by monsters here while on duty.
The group first travels to Mt. Roneal in order to activate the passage ring located somewhere within the mountain in order to prepare the Outer Lands to descend into the Qliphoth. Near the entrance to the passage ring, the God-Generals Arietta, Largo, and Legretta await the group in order to prevent them from operating the passage ring. They fight, causing an avalanche that swallows the group and oracle trio. When the group regains consciousness, they find themselves at the entrance of the passage ring, protected by a Daathic Seal, while the God-Generals fell into a nearby ravine.
After unlocking the seal and operating the passage ring, the group discovers that Van Grants has prepared for this moment, as memory particles begin flowing in reverse from the Absorption Gate. They realize that Van had been waiting for them to connect all the Sephiroth, allowing him to take advantage of the power and stimulate the core. In doing so, he could destroy the Tartarus and strengthen the Planetary Storm. Because of this, the Outer Lands, apart from the Absorption Gate, become in danger of collapsing.
