Was messing about instead of going to bed and got this one: WwSKfMSxG0
Bonemass, Elder, Eiktyr ofc and Moder on the same island more or less. But some bridges (or swimming) will be needed.
The starting island is truly massive with many many mountains, a giant plains, several swamps and even several mistlands.
Trader very close, but boat needed.
You can with bridges walk all the way to the end of the world in the south i'm fairly certain.

Also my personal favorite, it's got a lot of rivers that always make for really great views.
