Foresight

Foresight, often in the form of a Prophecy or a Vision, is a type of magic. It’s very race gift, only a few possessed this magic.

It featured on ABC's Once Upon a Time. It first appears in the “Pilot” of the Season 1.

Description
Foresight is the ability to see future, but it is only possible to predict the outcome or view incomplete portions of visions. The Seer considers the power as an unwanted curse. ("Manhattan", "Smash the Mirror")
