According to the information available in Armhands, which was not little, let alone bad, considering it was an alien organization, Zocarro was an A+ world.
What did that mean? Well, it was an excellent rating.
The world's classification, most common in this galaxy, took into account many factors, from the presence of living beings to the existence of cultivable energy on the universe's planets.
A planet with no conditions for the development of life and no energy that could be absorbed was considered the commonest type of world, classified as F.
After the F classification came E, followed by D and C, then B- and B+, up to A- and A+.
The Spiritual World should be a B- or B+ world, but Minos' staff wasn't sure yet, but it certainly wasn't below or above that.
