Gatshadow Mountain

Gatshadow Mountain is an enormous mountain in Tal'Dorei at the southeastern tip of the Cliffkeep Mountains, just northwest of the Bramblewood Forest and Westruun. After the Chroma Conclave attacked in Chapter 4, the ancient black dragon Umbrasyl roosted in a cave at Gatshadow's peak, receiving tribute from Westruun.

Several scouting parties from the Herd of Storms were sent to Gatshadow in preparation for an attack on Umbrasyl, but they didn't return. Later, Shale and some other warriors from the herd scaled Gatshadow, as well. Shale's age and disabilities slowed her down, so she survived Umbrasyl's slaughter of her party by a twist of fate, then descended from the mountain in time to meet Vox Machina. Together, Vox Machina and Shale ascended Gatshadow and slew Umbrasyl in his cave.
