Tower of Shadow
A runed, black tower that cloaks the sky in darkness.
This is a tower of twisted and jagged metal bands of various thickness, which are covered in arcane runes and symbols. The tower is made up of different metals, but should be considered to have an average hardness of 10, 180 hit points, and a break DC of 24. A Knowledge (Arcana) check result of 15 or higher reveals that the symbols are of Evocation, Conjuration, and Negative Energy. Detect Magic reveals three Auras (1 strong Conjuration DC 24 Knowledge (Arcana), 2 faint Evocation DC 18 Knowledge (Arcana)). The tower stands 300 ft tall and 50 ft wide at the base, narrowing towards the top. There are no doors to the interior of the structure, however, there is an open area inside the base.
