I am still marvelling at the beauty of the island of Artaeum. Although we are not to know where it exactly lies, there are some signs and landmarks that lure into interpretating its location. For instance, we have a coastline, three moons/planets and multiple triangular asterisms in the sky. Somehow I am inclined to think it's been removed to Aetherius or one of the demi- or pocket-planes 'between' Mundus and Aetherius.
So has anybody any theory as to where (or even when) Artaeum is?
...und Gallileo dreht sich doch!
