The Pillars

Probably one of the most spectacular and vast features of Edarneor, these rock formations usually rise straight from the sea, just off the coast. A desolate and inaccessible place as it is, rarely visited by mankind, it serves home to numerous bird colonies and unique flora.
Some winds can also be harvested only here.

Here's a bit more detailed account of the landmark's origin from one of the inhabitants. https://www.artstation.com/artwork/D9lRE
