Back from the dead for Snelf headcanons bc Skyrim is my coping mechanism rn
The order of Jephre had no magnificent chantry but a hidden grove very similar to the Eldergleam Sanctuary. Bosmeri exiles from Valenwood weren't uncommon to see there, but they often worked to repent for their exile. The priests would tend to the hidden natural wonders across their landscape and soothe the spirirs of nature. Or even answer their requests to promote peace between the parties.
Archivists fell under the order of Xarxes. They were known to keep archives in a few major cities, but not just anyone could wander into their collections. Obviously, they were protective of their secrets and knowledge, so only highly esteemed snelves could have clearance. Even if they had permission, they were still highly monitored. Good luck stealing from their archives when they stood.
Initiate Paladins had grueling entry exams such as the pilgrimage of the Forgotten Vale, but it went much further after that. They'd be made to sit in the cold with just their robes and recite teachings of Auriel. Usually, their training sessions were held during the day so Auriel could witness.
Trinimac wasn't as popular as others in the Falmeri pantheon, but his order was far from weak. Those devoted to Trinimac often pledged to uphold the image of an honorable warrior like their patron god. However, they could be a bit brutal at times, so they were effective executioners of justice.
The Chantry of Magnus was theorized to be where current day Winterhold stands, but scholars debate on the myth.
Magnus was very popular among any mage in the Falmeri dominion. When a Snow Elf won a magical duel, they'd give thanks to Magnus for their survival.
Necromancy was looked down upon unless it was for channeling purposes. It was a rare practice but often used for guidance from previous masters in desperate times. In all practices, they tried to steer away from using a corpse. They viewed it as tearing the soul from Aetherius.
The priests and priestesses of Mara cared for children orphaned by their mother perishing at birth.
Interestingly, there was a phenomenon coined by Falmeri healers called "Mara's Rage." It was said when a falmer was horrifically assaulted, Mara would give the victim a piece of her aedric anger. Her anger would fuel the victims, and they would pursue their assiliant for revenge.
Syrabane's order was very popular among alchemists and healers. His legends of warding off disease were the inspiration for many young apprentices to begin their studies.
