After signing the contract, Marvin arranged temporary accommodation for Babas and the others and, incidentally, took Sakar to the backyard to meet Ailan for the first time.
As soon as Sakar saw Ailan swaying in the wind and facing the sunlight, it screamed, waving its arm-thick rhizomes and repeatedly calling out 'ancestor', overcome with excitement.
As the former God of Honesty, Ailan couldn't possibly be an ancestor of the Treant Tribe, but Sakar likely thought so because of the influence of the Alchemy's Tree Seed.
Ailan, having merged with the seed, underwent a complete transformation, and the Cucumber Seeds it produced were the key treasures that helped Yuniya complete her first awakening.
It could be said that Ailan played a significant part in Yuniya's successful rise to genuine divinity.
