The old traditions provide us a simple but perplexing ritual for the animation of matter. Certain figures can be brought to life via the use of a carved pumpkin. But... how? Why? A pumpkin is just a gourd, no more powerful than any vegetable! So then, perhaps it is the face carved into it that affords it this power?
Maybe some roaming spirit chooses to make the facade its own? Perhaps the face itself is a macabre symbol that draws upon the great curse of Undeath?
I will dissolve a Carved Pumpkin to resolve this matter once and for all.
Update:
The Carved Pumpkin refuses to release its Power into solution. I feel certain that with the right apparatus and a solution of Soul Power, a Spirit might be brought forth. I will continue to investigate this matter...
