This is part of my speculation as to why the unrevealed pyramid ship race might actually be the Nine. Rhea is Saturn's moon which is heavily cratered and has wispy markings similar to the unknown planet and the Cauldrons of Rhea are referenced in the Grimoire. A cauldron or caldera is a massive volcanic crater caused by explosive volcanic eruption and surface rock collapse into an empty magma chamber(Source: geology.com) which may appear as large dots on a planet's surface. I would appreciate hearing your thoughts.

The small craters(small dots) on the planet's surface are likely to be impact craters meaning they are formed through the collision of a meteorite and not volcanic eruptions unlike calderas. However, the larger dots are more likely to be formed from a volcanic force meaning they are calderas.
