There are several areas I like but not sure which one or 2 to make my main base.
Some areas I liked and / or considered:
That area near Sepemeru on that hill that is all flat.
The flat area northeast of Sepemeru the flattest land with good resources I could find.
The area near that 1 iron node in the west side of the river region.
The island near the sentinels that is flat with the bunny creatures.
The flat land south of new Asgarth.
The southern island with the bears in the highlands inside the sanctuary castle ruins.
The Docks in the jungle.
The Silk Forest
The island west of the jungle with pitfall pass.
The flat land near the arena.
I also liked the passage with the iron.
Those are areas I liked or considered. Not sure where to put a base.
