Make a concise location description of a eerie scene outside a town tower with a basalt obelisk and a tower.
assistant
A black basalt obelisk is imbedded in the hilltop and stands as a shadow against the night sky. Just to the south, at the very crest of the hill, rises a circular tower of granite blocks. The northern ledge of the hill gives a fine vantage point from which to view the town laid out below.
