Adventurers plops, ripe for the grabbing

once in a thousand years, 1 or 2 people are born with limited precognition. these ones lead their lives inconsequentially. However, it has not come thus until now that two have found each other and brought offspring.

A seer can scout ahead, projecting their mind to any location and see events that take place. The greater the distance, the greater the perception. Meanwhile, seers have limited precognition of events happening directly in front of them, being able to predict, at the most, 1 to 2 seconds ahead. As well, they are poor fighters, unable to perceive the world around them when scouting great distances, great futures. This one will have to be led by collar or on horseback during their trance, and if worse comes to worst, be punched awake. The greatest limitation, or perhaps their greatest strength, is that they cannot see their Own future, completely unfettered by destiny.
It’s from this vantage point that I believe someone can have them be a narrator, being able to see current and future events through their mind’s eye one moment and being thrust into battle the next when their group encounters highwaymen.
