With the two most powerful and influential women in the elven kingdom as concubines, Andrew faced no obstacles to absorbing the divinity from the body of the deceased god they were guarding.
Indeed, they alone couldn't make such an important decision without consulting the other members of the elven council of elders. It wasn't difficult to gain their consent, and that wasn't just because of the words of these two elves.
The elves are one of the longest-lived races in this world and one of the few races that preserved their historical records after the war a thousand years ago, so Andrew simply had to tell them the truth.
With Crhono's approval, he revealed the existence of the fallen god, as well as his plan to destroy him. Andrew also revealed his identity as the candidate for god Eros and the future god of this world.
