[@BespeckledCeph] obvious yes ;) 
[@ihinka] There is actually no encounter of natives so far and I did not write anything about them. xD I'm open to it though if you can write a short lore about them. We can put in a story to introduce them to the outside world. It will be interesting to see how natives had lived in a dangerous hollow earth.

edit: Or even to the extent to give them a new language xD
