The Séftnes (Ingerish: the quiet) is a creedless faith which is prominent in Myrcia. The Séftnes is founded on a commitment to shared quiet in worship and to living lightly on the earth. Members of the Séftnes meet in a Séftneshús which is often a simple building with one large room in which worship is held. There is no traditional hierarchy in the faith but each Séftneshús will have a group of members who are responsible for beginning and ending meetings of worship. It is estimated that approximately 35% of Myrcia's population are members of the Séftnes. The administrative centre is the Séftnes Centur in St Wulfram, Dunwic ( ) whilst the largest Séftneshús in which state funerals are held is the Myrcia Milén Séftneshús in Núburh, Dunwic ( ).
Æmettafést (24 December) is the Séftnes winter festival which takes place at a similar time to the Kirk Myrcia's Dréamhealdende. Members of the Séftnes gather together on common land (often on cliffs and beaches) to partake in a time of silent worship and thanks for the year past. After this a bonfire is lit and fish and potatoes are cooked for those gathered to share.
