POV PunkGuy:
The tall black tower with rough walls that looked like the walls of a volcano stood on top of the tall peak, reaching all the way to the sky, its tip piercing through the thick black clouds circling around the tower.
Its insides were hollow, filled with a long spiralling path, twisting and curving all the way towards a large platform on its top. The interior was dark, with the only light source being a dim red light coming from a blazing hot ceiling heated by the giant dragon lying on the tower's roof.
All the way at the bottom of the tower was a gaping black circular hole leading into the depths of the mountains, connecting to the artificially made cave system used by the dragon cult as a base.
Howling and screeching echoed through the hollow interior, dozens of reptilian eyes glowing in the darkness. Scratching of claws coming from the dark corners as mutated draconic monsters walked around.
