Sooner or later we'll have to learn about the physicality and such of materials extracted from poltergeists. I assume Spender's read a book on it or something.
Also, important note!! I've been getting reports about the RSS feed. It is not broken, it just changed to a new one when I switched off of WordPress, unfortunately. You'll have to resubscribe to the one linked on this, the new website. Sorry about that! I'm looking into putting an announcement post on the old feed, but that might be lost for good (it was an automatic thing WordPress did so I don't know exactly how to access/alter it).
Thanks for reading!
