Just because we now control the Heart of Petrification doesn't mean there aren't other matters to take care of.
We need to rearm our troops. The Reians have blacksmiths who can make weapons for us, but they face a problem. To make their special weapons, their forges must be particularly hot. The only fuel that is sufficient is Dragrint's White Charcoal.
They are already killing Flame Dragrints for it, but they need help. If you join their efforts, you will be aiding them and us at once.
Our current arms supply is holding steady for now. But I am certain that will change soon.
The Reians need Dragrint's White Charcoal, and we need the Reians.
Hot indeed! A charcoal that burns on its own! No wonder the Reians use it.
This should be sufficient. Between this and what they already have, they should start forging weapons immediately.
Your advancement of our war effort will not go unnoticed, by me or by Sanctum.
Collect Dragrint's White Charcoal and take it to Coron.
[%collectitem]The Reians need fuel to forge weapons. Kill Flame Dragrints for their Dragrint's White Charcoal.
The Reian Tribe asked Coron for aid in procuring fuel so they could make the Elyos new weapons.
So you killed Flame Dragrints and turned in Dragrint's White Charcoal. Coron was pleased at your efforts for the war effort.
