One of the most remarkable magical events in Glorantha occured a little over a century ago – the Syndics Ban. Here’s the Lunar account: Fronela was visited by disaster in 5/37 when the God of Silver Feet was assassinated by a conclave of seven powerful priests. This blasphemous act brought the Syndic’s Ban crashing down on the god’s entire sphere of influence: Fronela. All of Fronela was laid under a ban of communication. Movement was restricted to their own territory. The precise definition of this territory varied from place to place and culture to culture. But few people ruled lands which were more than week’s ride across. Neighbors became memories, and all of Fronela was forced into a solitude of peace, cut off from even their allies.
Outsiders who attempted to enter Fronela from any direction where either diverted or killed. The only successful penetration of the barrier was by the Moon Boats, which charted a perilous journey across the hidden lands.
