This is an ancient portal that was discovered by the natives in this harsh environment. They have built a village around it and it has become
a hub for smugglers, mercenaries and monsters from all over the world. It is where you get your new quests... if this was an RPG game :)
I wanted to add a lot of details and I do realize that the composition got a bit messy...but I kind of like it.
I have used and modified some models from an old "kitbash3d" kit called "savage"
You can see some of the visual and stylistic experiments that I did along the way (image 2)
Cheers !
