The Alerunner runs east from the Mountmirror into the Malenkean. Commerce between lodge houses is most vibrant in the spring and summer months, and during this time the Alerunner is the busiest freshwater shipping lane in the Beast World. The river’s name comes from the goods it carries: southern grain fields ship ale, beer, and vodka north along its waters. Oric shippers often travel straight to Glasrún and Arneria from its estuary.
