Lind's mind was whirling through many thoughts as he returned to his quarters. A Divine Will had touched on a phoenix or emerged in one and created the Rebirth Grounds to give their race an opportunity to advance.
It also explained the abysmal success rate. Very few souls could withstand the power from the Divine Realm. Haro also confirmed his guess.
Yet, a spirit was attached to it which meant there had to be more to it than a simple refinement or breakthrough of the final bottleneck of the Immortal Realm.
The issue was what were its parameters. A natural spirit was much closer to a living being. It was born into the world and grew under the conditions that spawned it but would be able to be reasoned with.
In other words, if the spirit had been born during the process of the Rebirth Grounds emerging due to Heaven and Earth, he could possibly explain why a dragon was attempting the process.
