So, I'm solidly in the midst of my Gatecrashing campaign (I just got my first PC fatality last session! Whoo! And it was hilarious.) and I'm in the process of designing my next scenario to put my PCs through. And, thanks to being a detail-oriented, fastidious GM, I'm currently stuck on an aspect of my next planet design: Oxygen.
Specifically, how much oxygen is too much oxygen? If the atmospheric pressure is in the range of 3 bar, with a carbon-based biosphere on a habitable moon, at what point does the atmosphere itself become a spontaneous combustion risk, from lightning strikes, if nothing else? And would it be breathable by any sort of biomorph at those pressures?

- Zen Pools; Tree-like plant; creates large networks of forest that mutually supports themselves as they grow in height; can create large networks of woody regions that reach nearly a kilometer in height and hundreds of square kilometers in extent; rather than pump water up from their roots, they create large pools up at the canopy level to capture rainwater.
- Balloon Bombs; disaster flora; colonizes an area very quickly after a fire. Propagates by creating a floating seed pod filled with hydrogen, which pop quickly in the presence of heat, scattering the seeds on the fresh ashes.
- Aerial plankton: an umbrella term for thousands of plant and animal species that stay aloft on winds and using air bladders. All of the species are highly mobile, and use various strategies to use the storms and fires to their benefit.
- Fire Caps; a type of creeping vine that is rich in flammable oils. It requires fire to open its seed pods, which resemble small dark mushrooms or umbrellas approximately 5 cm across; these float away on the updrafts to colonize new areas. With proper filtering and treatment, the oil is edible by transhumans, and has a rich, smoky flavor when used in cooking.
