Agate Mountain

Template:Infobox LocationAgate Mountain is the mountain underneath which Darkstalker was trapped for about 2,000 years. It was the tallest mountain in Pyrrhia before an earthquake created a landslide and collapsed part of the mountain, leaving Jade Mountain as the new tallest mountain on the continent. This was envisioned by Clearsight when she contemplated her futures. This mountain is in the Claws of the Clouds Mountain range, within sight of Jade Mountain Academy as demonstrated in Escaping Peril and stated in Darkstalker (Legends).

Trivia

An agate is a cryptocrystalline variety of silica, chiefly chalcedony consisting of a large variety of colors and types.
It is possible that all of the mountains in the Claws of the Clouds range are named after gems.
Agate Mountain isn't in the Darkstalker (Legends) map, despite it being the tallest mountain in that time period.
It is likely that the fall of Agate Mountain caused the disappearance of most of the old NightWing Kingdom coast.
