Portal into the Future
This spell enables the magic-user to get rid of a meddlesome foe by flinging the target into a one-way portal into the future. If the target fails a saving throw versus Spells, the target is flung into the future… it is a one-way trip, though the victim can find another way back in time, if such exists. If the target makes the save, he or she jumped out of the way of the portal, and the spell fails.
The victim, if flung into the future, arrives at a random safe point on the same planet, d100 miles distant from the original point of the spell per level of the caster, in a time one century in the future per level of the caster, +/- d100 years. The caster does not know when the target will arrive in the future; similarly, if the caster is alive when the victim arrives, the caster has no clue, until this is discovered through normal means.
The caster physically ages one year per century the target is flung into the future, rounded up. For a human caster, this can be quite dangerous, if he does not have access to potions of longevity; for elves and other long-lived beings, such as shape-shifting masters of darkness, such effects are of little note.
