As you touch the gem, a deep voice resonates in your mind.
"Mortal, heed this plea. I am Eranikus of the Green Dragonflight, keeper of this accursed temple. My charge to ensure that the trolls never again bring forth their abomination of a god has for now ended in failure. As I imbue this gem with part of my essence, I sense my grip on the Dream twisting into chaos. Please - place this gem into the essence font in my lair, and let our magic there purge the taint from my psyche so that I may rest."
You place the gem inside the essence font.

"Mortal, I implore you! Find one of the Green Dragonflight to stop this... help me... I am chained in darkness... forever in agony... please do not torture..."
