Four stars

The Four Stars are central to the world of Mirosia, stationed along an axis at the center of the plane - the same axis on which the Isle of Mirosia is built. Each of the stars draws power from an elemental plane, releasing it and fueling the natural processes of Mirosia.

The Fire Star
The Fire Star is a portal to the elemental plane of fire on it's front side, and it has a dark back side. The Fire Star releases the most critical ingredient to life in Mirosia - light and heat.

The Fire Star is the uppermost star in the axis, placed thousands of miles above Mirosia, safely dispersing it's heat across the plane. Although scholars theorize that Mirosia might get colder far away from the Fire Star, no explorer ship has ever gotten far enough away to confirm this theory.

The Sky Star
The Sky Star is attuned to the elemental plane of air, releasing winds from it in a pattern that forms an "eye of the storm" around the Isle of Mirosia. This creates an important buffer that prevents anything, except possibly a limbo field, from crashing into the Isle itself. While they will deflect islands, the winds here are gentle enough that a flying ship can navigate without great difficulty.

The Sky Star is practically invisible at most times - as a vortex of wind, it's difficult to spot, but it can be seen when mists, storms or dust occasionally get caught up in it.

The Water Star
A spring located at the bottom of the lake atop the Isle of Mirosia. Water flows out of it constantly, straight from the elemental plane of water, feeding the waterfalls of Mirosia. This water is fresh, though the oceans throughout the rest of Mirosia are indeed salty.

The Earth Star
The earth star is buried deep within the roots of the Great Vine, which holds Mirosia in place. It provides the strength for the vine to continue to do this, and also radiates nourishing energy that feeds plants throughout the Shallows, providing them with much of the energy they need to grow.
