Flag of the Chantry of Auri-El
The Chantry of Auri-El is an isolated, but vast series of temples located across the Forgotten Vale. It once served as the epicentre of the Snow Elf religion, the chief deity of which was the Aldmeri god Auri-El. The Vale is a large glacial valley hidden deep within the mountains on the northwestern Skyrim peaks of Haafingar and the Western Reach of High Rock.
Unknown Book, Vol. III
It is unknown to us if the Snow Elves had a 'capital' though many scholars currently interpret that the mythical Chantry was the closest thing they had. Said to be built of monolithic slabs of the whitest marble adorned with black. The scraps of encounters the College has recovered said in its heydey the Chantry could hold thousands and was a place of worship, festivity and political entanglement.
The palace was named after the main deity of the Snowelf pantheon, Auri-El (Akatosh to those who follow the Nine Divines). It is said he has a large statue of himself holding the 'Sun of Auri-El' at the Chantry of Auri-El in the Forgotten Vale of Skyrim. Initiates would go to all six Wayshrines to collect the water contained within them with an Initiate's Ewer and eventually reach the Chantry. After pouring the water within the basin of the Chantry they would be granted an audience with the Arch Curate himself. Following a massacre by the twisted Falmer most of the worshippers and prelates were killed. A group of Knight-Paladins were led against the assault but quickly defeated. The last known Snow Elf survivor to continue to worship Auri-El is Knight-Paladin Gelebor, though the prelates of the chantry in death also worship him.
On the Ancient Falmer
The Sun of Auri-El is said to have adorned the flag of the so-called Snow Elves. Ice-Blue in colour it was decorated with an elvish knot, similar to those found on recovered and Ancient Falmer Armour. The field is said to have been an off-white and the sun was flanked by a blue elvish pillar.
