Yes

The crypt seems to be old and falling apart, but as you approach you find that there is a single stone casket. It is sealed with many chains that converge on a single lock.

You idly touch the lock, pondering what is inside when it makes a loud click, the chains falling away. The lock begins to rapidly rust, falling apart into a pile of dust. You feel an overwhelming presence as the tomb opens, black mist pouring forth, forming into a humanoid figure.

You feel yourself unable to run as a skull appears in the mass, moving to take its place as the head. It looks down on you as it speaks. "I am the great mage of the eternal towers. I was imprisoned here over five thousand years ago. My power was so great that i could not die though over so much time my body wasted away and was destroyed. A warning to you, young one, immortality is a myth. One must have sustinence to survive. Now, I have no way of remaining in this world, but my power needs a vessal or it will slowly destroy everything around me. For freeing my soul i give to you all my magic, all my power, but none of my knowledge. You must learn to wield it yourself. Normally this would instantly kill a living being, but you lack magic entirely. This makes you an empty container my magic can fill. You only need to accept it. What say you?"
