Why Did the Flame Wane?

The work progressed slowly. 

There was no day or night in the Sky Below, and Sunny did not particularly care for tracking time anymore. He only knew how much of it had passed because of the happy shadow, which continued to act as Rain's guardian somewhere far away.

Sunny was not trying to decipher the ancient script blindly. He was familiar with many variations of the runic language that had been used in the Dream Realm… or rather, in the multitude of realms that would one day become its various regions. The languages the people of the bygone eras had spoken were different, and so were the writing systems they had used.
