Also known as a knot or a bight, a Crossroad is a place in time which could potentially split into an unexpected direction. Seers and prophets are used to these, as the The Tapestry is how prophets and seers refer to time. It looks like a giant glowing tangled knot with light-like threads constantly changing, tangling, and altering paths. It's nearly impossible to predict with 100% accuracy. There is a reason Merlin refers to fortune-telling as "very good guessing."... always shows numerous possible outcomes. Crossroads, however, are a big deal; they don’t lead to minor changes, but enormous transitions of power, or direction, or weather patterns, or any other large number of differences.
