Skyborn Altar

Description
Skyborn Altar is located east-southeast of Morthal, south-southwest of Dawnstar, atop a mountain. It's also the location of a Word Wall - Frost Breath.

Notable Loot

 * Treasure chest behind one of the pillars on the left (facing the word wall), containing random loot. There is a single burial urn adjacent to it.

Quests
A courier may give you a letter from a friend to seek out this location.

This can be one of the locations for the Dragon Seekers quest given by either Farkas or Vilkas.

Bugs

 * When approaching the word wall the animation triggers and the word is learnt but when you access shouts the word is not there to unlock so you can't learn it.
 * If you happen upon the book N'Gasta! Kvata! Kvakis! prior to getting the quest from the mages college, leave it be, otherwise it'll glitch at (in my games situation) "find the copy" even if it's in your inventory, the game does not register it and still assumes it to be in the chest.
 * When coming back to this location several times, it will be impossible to get the soul from the dead dragons on the lair.
 * It's impossible to learn the word on the wall, you are in front of the wall and hear the "wind & souls", but the animation does not start.
