Fandoms: Supernatural and Merlin
Rating: PG (Gen/optional pre-slash)
Word Count: 33,935
Setting/Spoilers: This is set between S4 and S5 of Merlin and around S8 of Supernatural (in an undefined fantasy time period where Dean, Sam, and Cas are all available and doing alright.)
A/N: There's about as much merthur slash in this fic as there is in Merlin - which means that technically, it's pre-slash.
Summary: When a sorcerer summons monsters from another world, Merlin must summon heroes from another world to help save Camelot. Meanwhile, Dean and Sam Winchester didn't even know they were summon-able.
