Each great plane has its characteristics, and Danaila was originally adept at defense.
A million years ago, during the invasion by Abyss, Shadow, and Ash, it was the pinnacle of Danaila's era. After that battle, Danaila was severely damaged.
The invading three great planes fared no better, a scenario described as mutual devastation, with the Ash Plane suffering the most serious damage.
Among several planes, Ash was the weakest, and the consequences of the battle were more severe than expected. Its strength constantly waned over time, eventually unable to maintain the status of a 'great plane'.
At a critical moment, as Ash's most loyal Guardian, the Shadow of Annihilation stepped up, merging with the Ash domain.
Thus, Ash managed to maintain its status as a 'great plane', but from that day on, Ash was no longer the original Ash, and everything within the plane quietly transformed.
In any case, the Shadow of Annihilation could be regarded as the savior of the Ash Plane.
