Mountain Spire is a location in Tyranny. Note that this article concerns only this specific Spire. For a general overview of Spire functionality, see Spires of Terratus.
You blink away the last of the luminescent trails in your field of vision, the masonry of Ascension Hall is replaced with wide open space in every direction, save for the slab of ancient stone beneath your feet. High winds shove you, pushing you off-balance. The air is cool and thin - unsatisfying to your lungs.
Every way you look, mountains rise up along a distant horizon. The rivers and forest below bring to mind maps of Vendrien's Well, and you quickly trace the Matani, the Irenev, and all the numerous waterways of the region. Higher than you imagined it, this is indeed the pinnacle of the Spire at Vendrien's Well.
