earth eternal gold

Acquire four raw meats of four animals, which are raw beef (from cows), raw rat meat, raw bear meat, and raw chicken meat.

If you want, you can just open the door and head on inside or otherwise kill both of them. Inside, you will find the Cauldron of Thunder Sanfew was talking about earth eternal gold. Dip the four meats on it.

Now head out of the dungeon and go back to Sanfew. Talk to him with the four dipped meats.

After that is done, speak with Kaqueex again for your reward. Summing it up:

1) - Talk to Kaqueex in the Druidic Stone Circle. Talk to him about his troubles.

3) - Get raw beef (from cows), raw rat meat, raw bear meat, and raw chicken meat.
