Ethil's Wall is an area in the Dragonland Chronicles.
Although the great wall of the north bears the name of Ethil II, construction began several hundred years before his reign, as a first attempt to keep the orcish raids at bay.

However, a lurking shadow has been seen stalking the western reaches of the barrier, seemingly seeking council with darkened things, as if some treacherous and unspeakable covenant was being made...
