VSS: Dire Warning

You receive a message of up to 6 words from your future self, warning you of a critical threat or pointing you toward a fruitful avenue. At some point in the future, once you have learned why you sent the message, you must perform a 10-minute long ritual to deliver the message back in time to your past self. Once you perform this ritual, or one week later, if you don't discover this information. If you cast this spell and receive no message, it indicates that you never complete the ritual in the future, possibly owing to your death or some other hindrance.
