Righto, so earlier in the chat today, after the Cthulhu panic was starting to die down, Eli and I came up with the idea to pool all our knowledge of the Metaguards and ol' squid head into a single Google Document; that way, anyone who wants to write a fic in order to help with containment has all the information he or she needs to do so, and anyone who has something to add to the info already gathered can make an edit firsthand (that means you, everyone who created a Metaguard! Give us all the inside info on your creations you can spare!). The document isn't up yet, as I have no idea how to make one, but it will be soon, so everyone, compile that info and get ready to send it in!
(On a side note, here is an online copy of Cthulhu's debut story. The original link isn't too far down in the topic, but I'm including it here for convenience's sake.)
