Lucifer called me the King of the sands (my trial was going through multiple death events) one of Ben's Titles is King of the Ash.
The trials of the Goddess, Gods, around 12 I've heard exist, a test to become a Titan. A portion of the divine just takes in what id say is the somas, necters. Ambrosia. They would rather be at that stage, to cause either Chaos, or Order to do things. One of the trials is lifting the world, sitting on the sun is another.
The trials of the Titans... The Primordial Originator said that there are realms only known to them, I got to take many of the passageways the transcendental ocean is one. The crossing of the sands of time are another.
I know everyone one has been offered one of the tests even a mortal can be offered a Titan trail, rare as that would be.
