Question: is riverdale and sabrina in the same world?
Answer: Sabrina and Riverdale Are Set in the Same Universe - Sort Of Aguirre-Sacasa once shared in an interview (via EW) that there's no magic or supernatural beings in Riverdale but "on the other side of the mythic river, which is sort of like the River Styx, there's magic and witches and dark Lovecraftian horrors."
