Under Nasiens' captivity, Percival learns that Nasiens is developing an antidote for the miasma plaguing Echo Gorge, with the animals' mutations being an unintended side effect of his experiments. Deciding to trust Nasiens, Percival willingly drinks the untested antidote despite its potentially lethal effects. The antidote proves to be a success, and after Percival convinces the fairies of Nasiens' innocence, Nasiens spreads the drug across the gorge and restores it to its original state through his magic ability, Mix Venom. However, the gorge is attacked by Ordo, Nasiens' long-lost mentor and adoptive grandfather, who has been transformed into a monster under the control of the fairy creature whom Nasiens imprisoned earlier. Realizing Ordo is the true source of the miasma, Percival promises Nasiens they will return Ordo to normal.
