In the lowest level of the tower, you can find the containers, where the energy of the world, absorbed by the tower, was stored.
In the center, there was a giant pool connected to these containers which were filled with a liquid with a color that seems to be a combination between golden and purple.
"That pool is where the Elder Brain will remain. It is a combination between the energy of the golden flames and the one absorbed from the world. It is highly nutritive and it will allow you to use the Elder Brain's body at full capacity, as well as increase its power and help it make a biological advancement to the next Rank."
Zatiel pointed towards the pool and signaled for the Elder Brain to be submerged inside it.
Dante did not hesitate and manipulated the Elder Brian to enter into the pool, and the moment he did, he felt how it was being enhanced and was constantly replenishing its energy.
