The fetch can see the pledges that the changeling has sworn, and can fool the Wyrd into thinking that the changeling has broken them. This power is terrible, because it (temporarily) makes the changeling into an oathbreaker, but the consequences for the fetch are dire as well. To use this power, the fetch must first understand the pledge; this requires that the player rolls Intelligence + Wyrd while looking at the changeling. The fetch then takes an action that breaks the pledge, as defined by the pledge’s tasks (see Chapter Three of Changeling: The Lost). The changeling immediately suffers the sanction of the pledge, but whatever that sanction, no matter how dire, it only lasts for one day. Even if the sanction is blindness, deformity or loss of Wyrd, the changeling returns, hale and healthy, once the Wyrd has time to correct itself. The fetch, then, suffers the sanction itself — permanently. The only way for the fetch to avoid this fate is if the changeling dies before the sanction is lifted.
