ígnus is the closest planet to Lumenoferos. The extreme heat makes it uninhabitable outside a few canyons closer to the poles (where several research stations are stationed). In orbit, there are many artisan space stations around it, as the extreme solar radiation can be used to speed up several alchemical processes that yield lucrative materials; repositioning these stations into the planet's shadow when necessary makes long stays safer.
