|Alias||Highway of Creation, 4th Dimension|
The Astral Sea is one of four dimensions of Nawirrûs. It covers an area equal to the size of the Core Dimension; the one with stars and worlds. Since the Dawn Era, the Astral Sea has served as a highway for funneling energy and matter from Chaos to places in the Void where Creationists built and continue to build worlds. Without using this dimension, where travel can be many times faster than traveling the Void, they would not have been able to build anything beyond the Elemental Ring Worlds in the time that they did.
In the Astral Sea, trajectories are all over the place, with things moving about in all directions, some on a steady course, others drifting aimlessly. Forward impacts are largely prevented, or dulled, by the bows of astral ships, or by traveling a much slower speed. The problem with traveling slow is the vastness of the area around, as big as Nawirrûs.
