Charlie should run a hunter wiki, with all the lore every hunter has access to, with info about how to kill everything.
I support this 100% and would donate to her Kickstarter.
Wouldn’t be very hard – she could piggyback on Google or Amazon’s servers for the space and encrypt it against normal people/demons (not that demons stood a chance anyway but imagine making anti-demon sigils into code. IMAGINE *HEART EYES*). The tech upgrades for hunters would be epic.
