History[]
Xenocide[]
After Planter's sacrifice to test whether the Pequeninos required the Descolada for sentience or not, Glass served as the experimental subject to test the Recolada. He lived for three days in an isolation chamber. After this, he was "Planted" by other Pequenino brothers and became a Fathertree, proving that the Recolada could effectively replace the Descolada on Lusitania with no harm to the life cycle of the Pequeninos.[1]
