The largest river in Tyrwingha, it runs out of the Mostreve Hills towards Tafolwern. The headwaters of the Aben are a hilly land of many small streams and good timber; there is also a major garrison of the Army of Mostreve, the Aben Garrison.
The Aben runs for about a hundred miles through the Tyrwinghan countryside before the Trellyn joins it thirty miles south-west of Tafolwern.
