Ancient City

bedrockAn Ancient City is a generated structure found in the Deep Dark, harbouring loot chests containing items that cannot be found anywhere else. It is made up of long corridors with wool floors (which prevent vibrations), as well as some smaller ruins off to the side of the main corridors, which contain 1-2 loot chests. The central point of the entire structure features a large rectangular structure, which resembles a Warden's head. The central structure also contains reinforced deepslate, which is currently unobtainable in Survival mode.

Structure
The city features a massive palace-like structure that stretches throughout the biome. Unique blocks (Such as Reinforced Deepslate) as well as different forms of Deepslate can be found here. The loot which can be found in the chests, currently contain several useful items for exploring the ancient city, such as snowballs and the new enchantment; Swift Sneak.
