The adventurer rode into the golden-hued glade, looking around. If the tribesman he had 'persuaded' to help him hadn't been lying, it should be here. Ah, there it is, he thought. A small pool, with no inlet or outlet. Dismounting, he looked into the crystal-clear water. He could see goldfish swimming around, and beneath them the bottom was covered with golden statues of men and women, mostly nude but some with a kilt or loincloth.
“I'm rich,” he exulted. “That damn tribesman didn't die in vain!” He stripped off his clothes and armor, noting in passing that the ground was mounded, here and there, with weapons, armor, and other items, mostly rusted or rotted by time, and dove into the pool to begin gathering up his wealth.
Silence fell over the glade as the new statue settled onto the others littering the bottom.
The villagers are having a fit, they've found something in the woods!
There are many scret places in the old forests; the least of which is by no means Old Stone Face
Alia exclaims, "What a gruesome sight!" and points to a brook filled with gravestones - some still upright while others are knocked over.
HomeTrees, there is nothing more Elven. These enchanted trees are one of the three Keystones of Elventi Society; allowing Elves to live in harmony their beloved forests. Without them, there would be no Elventi Society.
With a huge number of sacrificial victims, another realm long ago secretly bound a Prince of the land spirits, Iorstonn by name, thus ensuring the fertility, and improving the magical defences, of their realm. But binding that Prince to one spot has disrupted the weather and magical patterns (ley lines?) over half the continent. Things have become bad enough that a coalition has been formed to rectify the situation, once divinations have established the cause.
Your party is one of the teams assembled to do the rectification: find the binding object and steal it ("so that we can destroy it here in our realm, of course"...*) or destroy it over there. Presumably the Prince will be grateful to his rescuers and angry at the binders, but with a greater spirit like Iorstonn one can never be sure: such beings are "tricksy".
* Of course, the rulers of our realm might want to control Iorstonn for their own ends...
