Hey Beefermatic amigo!
I made them up, so you have come to the right place.
I can give you my brief thoughts on them, hopefully I will get to define them properly in the future
Cosmic Cyst: 8d growth attached to the 9th dimension corrupting multiple realities, a bit like blowing glass, except the surface of the Kuvachim is being warped and twisted. Detaching the cyst might ultimately cause the birth of a Fractal Wraith.
Star Plague: A dark energy 'disease' that would infect stars causing them to revert to nebulae, diffuse and spread out infecting other stars. So stars would seemingly pop out of existence and this would create something akin to a supervoid in space. Might be home to Dark Energy "Geists".
Probability Crack: 9 Dimensional Crack (likely caused by someone trying to penetrate the 9th Dimension or 9d collisions) leading to localized areas of improbability and the longer you stay there the more improbable the outcomes (ie. what are the chances a Goblin could kill a Time Lord).
Logic Paradox: Basically a metaphysical 'Pit' a being like a Time Lord could find themselves in. Solve a puzzle to escape (e.g. get the player to solve a Rubik's cube or stay trapped).
Anti-Maxim: 10th-dimensional echo that resonates within a pocket of 8th/9th dimensional space. For example "all hits count as misses and all misses count as hits/all saves are fails and all fails are saves, etc.).
Working on a few Omniversal Hazards as well.
