Great Arrow Mountains

The biggest mountain range in the Riverlands. Once home to a great Illithid and Dwarven empires in their time, now a shell of its former self. Thankfully, it became a natural barrier between today's states, making it problematic to have an all-out war. The legends state that this is the arrow fired by the Translucent Traveler that killed the Titan The Diplomat. The dwarves call these mountains - Riras-Feb-Onol, while the elves - Elandi'Ar.
