Nerakalis will have an atmosphere of 71% nitrogen, 28% oxygen, 1% Co2, and 1% ammonia. This is a higher oxygen level than earth, and of course, the Ammonia in the atmosphere does some interesting things. It would make metallic ions and nitrogen a lot more bio available, meaning bigger plants, with possibly some more metals in them (Which might help counteract the flammability of a high O2 world)
There's not going to be any sentient creatures on this world- but the plants, fungi and animals have a giant gestalt conciseness
