aturno occupies a small island, less than a mile in length, off the coast of Estremadura. The island is covered in gardens and orchards, with the sancta of the magi scattered throughout. Most of the magi have magical interests related to the sea or its creatures. Lentulus Bonisagi founded the conventum as a retreat where he could focus on his research in peace, but over the decades magi with an interest in the sea have accumulated.

Domus Merceris established a Sedes Merceris in the early thirteenth century, building a small complex of buildings and a sturdy pier in a cove on the south end of the island. One arched doorway of a warehouse is a Mercere Portal linking to Harco. A Merceris ship provides weekly transport to and from the fishing village of Peniche on the mainland.
