The Dark Chapel, dedicated to Tenebryll, was majestically created. Forged from pure obsidian, the structure looked more like a military fortress than a place of worship. It stuck out among the city like a stain on white sheets, with its towering black turrets and spots in the wall designed to grant people inside the ability to attack others from inside.
In a way, it made sense that the Dark Chapel had the design of a military fortress. Of all of the elements, Dark was widely considered to be the strongest. It had great offensive and defensive capabilities naturally, which is something that other elements typically did not have the ability to. Combined with the creation aspect that Tess only knew of thanks to the tomes she had read, as well as other things that very few people knew about, then Dark magic became a very formidable element.
