Fire Nectar is the highly poisonous nectar of a flower that only grows in the mouths of active volcanoes on Neva'Eh.
It is deadly when drunk and brings instant death to anyone who ingests it. It is part of the ceremony to become a Quad, drinking the neactar from a 10-billion year old goblet. The Quad Potential who drinks this nectar dies and is then reborn, if they can be recussitated, as a Quad. ONly half who attempt this ceremont survive.
The effects of this, on a body saturated with Aleptonit, is that the Quad magic that has been growing is now completely released.
