Since we live on a giant plant/tree, I don't see how earthquakes could happen. At least not so that we notice em up on the branches. Also, I dare not imagine the effort it would take to code random events like that into the game.

"It's shite being tryker! We're the lowest of the low. The scum of Atys! The most wretched, miserable, servile, pathetic trash that was ever shat into civilization. Some people hate the Matis. I don't. They're just wankers. We, on the other hand, are COLONIZED by wankers. Can't even find a decent culture to be colonized BY. We're ruled by effete arseholes. It's a shite state of affairs to be in, Marceline, and ALL the fresh air in the world won't make any ****** difference"
