Delta castle (Nether structure)

Delta castle is an idea for a new structure for the basalt deltas in the nether. Delta castles are very big in size. There are made of basalt and blackstone. It contains great loot. Inside are magma spawners. Maybe there could also be a magma boss or something. And there are many traps. Piglins, zombified piglins and skeletons spawn also. There are multiple rooms. There is even a room with a nether wart farm, magma sapwner room, maybe a boss magma room. Overall the Delta castle is very hard to beat.
