So, I just watched watched one of the Dark Crystal for the first time with my Grandkids. It’s (whichever one has the pic of old heavyset character puppet as cover. . I’m talking Jim Hensen puppet movie. So, there’s a part where the old vultures draw a Gelfling into a cave and they hook her up to pumps and use a crystal to drain the life from her and collect some sort of whitish fluid into a vial from her.

Now that I have learned alot on here, I’m thinking Adrenochrome.
