Which TTRPG system is this for?
The Year Zero Engine

What Stellar Phenomena did you use?
Black hole (: but I'm a little afraid I didn't lean into it as much as I should have

Did you participate in Hard Mode? Which extra rules did you use?
My ashcan verison of this doesn't have images, but may later, so I wouldn't count it as fitting the Hard Mode rule of 'no images or diagrams'-- or any of the other Hard Mode rules either.
