In order to decide which Species would be most useful to Devour, Cero and Raya had had to sit for quite some time on their way.
In the end, they decide on a couple to be made a priority, which include the tiny tiny trees which Cero went to find with Rea.
The reason for choosing it was rather obvious, as it was thought that it would complement Cero's regenerative ability, and it did.
Apart from that one, a couple more Species had been selected as a priority.
Lumen Vines.
