The ruins of Heibarr are situated on a branch of the Sellen River in the River Kingdoms, downstream of Mormouth in Pitax and upstream of Outsea. It was established in 3756 AR, eventually becoming established on both sides of the river, with a bridge in 4109 AR linking both sides. The settlement prospered until 4434 AR, when Mayor Aindon decided to build a toll gate underneath the bridge in order to tax river traffic in contravention of the third of the River Freedoms.
