The Wheel of Time - The Call of the Horn
The Illian Road is the name given to the highway running east from Ebou Dar in Altara across the border into Illian. The road does not run all the way to the capital of Illian, instead joining the Silver Road near the River Manetherendrelle. Due to the harsh terrain along the coast, the road runs inland, north of the Rhannon Hills and the Venir Mountains. The Seanchan fortified the road and positioned outposts in the hills and mountains to the south in preperation for an offensive against Illian, but were defeated in battle by Rand al’Thor and forced to abandon this strategy.
It is likely that this term is also used for any roads close to Illian and leading to or from the city.
