Overflow - It appears a massive structure made of a strange, coral-like substance, layered in such a fashion one could compare it to an especially large, layered jello mold, thus creating a strange, yet biological fortress shape in the vague image of a ring, with various walkways leading up to it along the sides, and strange fleshy outcroppings here and there akin to polyps, while there are strange, round-ish towers which emerge in certain portions. The role of windows is fulfilled by various porous holes throughout the structure, and it's surrounded by fields of various other odd forms of coral, all similarly colored in extravagant ways. Various spikes and tendrils emerge from the walkways and area around them to deter approach - it always created a large pit when channeled into a territory, and fills this pit with the Deep Flood, making the base underwater by default - though, like usual, other beings cannot swim the in the Deep Flood, and instead sink to the bottom - thus forcing them to use the walkways. The interiors are fleshy and coral-like like the exterior, but have a strange, almost cute look to them, with various floating, cute little critters here and there, comfortable shapes, and similar such things, along with much less cute things such as tendrils, barnacles which release acidic gout, and urchins which create massive spiked walls to defend areas. The interior is less reminiscent of a base and more a strange, extremely varied ecosystem with no real exact purpose to it, and various large, open chambers where creatures can be found aplenty are common as well. Of course, it is inhabited by the creatures of the Deep Flood in addition to its more benign wildlife, who strike out and attack all invaders while also breeding amongst themselves. It has no exact docking system unlike the others, as ship-type Deep Flood creatures can simply enter through the many holes that dot the environment. It has no central command center making it more of a pain to assault than other similar fortresses.
