Rootwalkers

(FROM BIBLE)
Have started planting themselves across the system
Considered deeply enigmatic by other species
Absolutely not unified
tend to congregate in patches
wanderlust comes upon them, though, as they don’t really have many needs that aren’t met by just sort of existing. But just sort of existing isn’t enough for many of them.
Ogres and Giants view them as bosom companions…or violent opponents if they actually deforest or burn an area.
Tend to shun fire elemental folk. Greatly.
Cultures tend to be relatively peaceful tribes.
Probably some scary mega bugs target them. Dire termites?
Life on their planet is either plant based or insectoid.
