Sul'Kun, the Art of Stillness

Also called Silken, Stillness, Quiet, and the Waking Sleep, Sul'Kun is thought to be an offshoot of Etrism that was coopted by Satari Drifters, though the practice has found its way into other faiths as well. Indeed, though many of its practitioners will speak of its value to prove one's devotion and facilitate spiritual insight, others might well argue it is not even a religious practice. The Shadow Watcher and Sagus Benne ai Ufriti praised the practice, despite an utter lack of faith.
As its names suggest, Sul'Kun is an appreciation and practice of stillness as a form of meditation, reflection, and discipline. Adherents use stillness to achieve calm, to consider new and old information, and to train their bodies to reject indolence or decay. This often manifests by sitting quietly alone, but many adherents will stop and stare into space at seemingly sudden moments, presumably when struck by a thought or when seeking to calm their emotions. This more than anything connects them to the mysterious Etrist faith. The most extreme Sul'Kuni will seek to maintain stillness in difficult positions: standing on one foot, hanging over a cliff, even when twisting one's body into awkward forms.
Sul'Kun is most strongly associated with Satariai living in places where the faith is not in the majority: the Vallian Coast, Northern Olveiria, and the Great Isles of Liddinawth are the most common examples.
