An oracle is a seer that has not only perfected the art of foretelling but can manipulate the flow of time itself, turning back time for a few seconds can save lives, allowing an ally to dodge a blow or avoid a trap. Normally found far from combat, an oracle prefers to study time and use their powers to make sure great evils are averted, just and honourable rulers are not unexpectedly assassinated and natural disasters cause fewer casualties.
Oracle called out to fight will aid their allies by speeding up time in their favour, to the enemy it appears that they are moving much faster than normal. If engaged directly an oracle can touch an enemy and accelerate time to much that they grow old, wither and die, but their greatest power is the ability to return to the past, to a time they have pre-determined by activating a Timeshard.
