Time Transposition
(Alteration, Summoning)

Range:  10 yards per level
Components:  V, S, M
Duration:  Special
Casting Time:  1 turn
Area of Effect:  1-foot per level radius
Saving Throw:  None

This spell takes a spherical area, and everything in it, forward or backward in time. The spell will move the caster as well, if he is within the sphere.
The spell will only move those affected through time, not through space. Therefore, a group of individuals will be moved to the same spot in another time. Note that this may cause problems for the recipients if those affected are moved to a time where a certain spot was, for example, an erupting volcano.
The spell will move those affected either forward in time up to 10 years per level of the caster, or backward in time up to 100 years per level. When casting the spell, the wizard will designate the number of years that he wishes to move those involved; but month, day, and hour are to be randomly determined within that year.
Note that if the caster uses this spell offensively against opponents, by moving those affected in time to get rid of them, they are not entitled a saving throw and magic resistance seldom affects 10th-level spells.
Also, anyone or anything that is only partially within the sphere of effect will not be transported to another time. Instead they will be violently thrown from the sphere causing possible damage.
This spell can also be used to destroy time elementals. The spell will permanently disrupt them, without any kind of saving throw.
In addition, those that are transported, willingly or not, will automatically lose one point of Constitution, permanently. Therefore, it is not a good idea to make various "merchant" runs back in time, where certain current technologies might fetch a high profit.
Lastly, it is up to the DM's philosophy on time travel as to whether or not changing the events in the past will alter the future. In other words, the DM must decide the outcome of the "If I go back and kill my grandfather, before he fathered my father, will I cease to exist" dilemma. It may be the DM's opinion that the person who kills his grandfather will cease to exist, or possibly it may be that a person attempting to kill his ancestor will be prevented from doing so by other circumstances. Again, the decision is up to the DM; just be ready for any character's experimentation.
The material components for the spell include a sanctified holy symbol from the head druidic god, an empty hourglass made from glass and mithril (value 500 gp), and a pinch of the essence of a slain time elemental.
