The Dust of Sages
When wise men are buried together, it is said their souls can be at peace. They will have endless discussion about all sorts of wisdom from the afterlife and beyond, much insight can be gained from them if you have the will to listen. In places where the dusts of these ancient men of wisdom congregates there can be a spontaneous eruption of new life. The birth of a new sage. The soul arises from epiphany in the minds of dead sages, rising from their mutual enlightenment and desperately seeking a body to inhabit. Typically, there will be none, and the spirit is weak, so it will garner a coat of dust for its body.
The Dust of Sages will then begin to examine its surroundings, searching every nook and cranny for another souls to learn from. Not finding one will cause panic as The Dust searches over and over again for something missed. This eventually spirals the creature into madness and depression, as, being a living thing, it no longer has access to the thoughts of the sages that birthed it, yet not courageous or powerful enough to leave the crypt of its own accord.
It is a pitiable creature. It possessed the wisdom of a thousand years of contemplation and discussion, yet has no outlet or muse. When at long last, the creature is discovered, be it by foolish treasure seekers or hardened adventurers, it will immediately seek to enter them and merge ideas. The Dust will fly up into their faces and assault their ears with the ideas of long dead men, things most mortal ears cannot handle or comprehend. It will sound like gibberish at first, but if The Dust is allowed to continue its assault the wisdom could prove maddening.
