Dimension Octogon

Dimension Octogon, AKA Dimension O, is a singular universe neighboring the Alternate UUniverses and is the namesake adopted home dimension of the Teadr 0 precursors to all mollusk beings, the Octogons, who relocated their homeworld of Octosis to the exact center of the dimension (Give or take 20ft). This dimension is only suitable for mollusks because it has a very reactive atmosphere and physical laws that cause gases to be very difficult to control and cause water, humidity and moisture to pop out at random times, causing sweltering temperatures, destructive storms, and flooding, but also nurturing for sea life including mostly mollusks, thus the atmosphere is nearly impossible for non-mollusks to survive in, allowing them to be the dominant species of the dimension.
