Nodacrux is a verdant world, with abundant water, temperate climate, a thick oxygen-nitrogen atmosphere, and a rich ecosystem. I would seem to be perfect for life. The relatively high percentage of oxygen makes humans feel energized and alive, though it has also allowed insect analogues to grow to frightful sizes.
Unfortunately, Nodacrux is a case of "almost, not quite." Thunderstorms are as common as on Earth, but in Nodacrux's thicker, oxygen-rich atmosphere, they are deafening and spark constant wildfires. More damning, however, are the large and ubiquitous tufts of pollen that float on the high-pressure air. In humans and other oxygen-breathing species, they cause severe or lethal allergic reactions.
Note: The Mako can land here. There are deposits of gold and cobalt here. There is a research facility here for UNC: ExoGeni Facility. There is a Turian Insignia that can be recovered here. A crashed probe can also be salvaged here. There are two Thorian Creeper groups, and an abandoned base with some salvage near one of those.
