Iriaebor is justly known as the City of a Thousand Spires, for fantastically bizarre, many-storied towers rise from all quarters of the city and are tightly packed together. As a result, it is possible to navigate Iriaebor via a network of arches, bridges, stairs, and leapable gulfs far above the city streets. You are well versed in the skill of navigating the skyroads of Iriaebor.
