Zion, Luna, Lars, Kaitlin, and Eliza all waited in front of the giant crack in space that was the Fracture. Fractures are ranked the same way monsters and mana beasts are, going from Rank 1 to 11. The way you know what rank a fracture is, is by seeing the color it gives off.
White is rank 1. Light Blue is rank 2. Dark Blue is rank 3. Light Green is rank 4. Dark Green is rank 5. Yellow is rank 6. Orange is rank 7. Red is Rank 8. Purple is Rank 9. Black is rank 10. And as for rank 11, the fracture itself won't have a color, but it will be ripped apart, space to the point where it resembles a portal. It would be clear if it were to have a 'color'.
The fracture in front of them was a Yellow Fracture, so rank 6. This also matched their strength since they were Master Stage Cultivators. But even though they meet the rank requirements, that doesn't mean they would have the ability to destroy the fracture, since they would be up against hundreds or even thousands of monsters.
