This spell actually sends characters back or forward in time. They can actually affect the flow of time as they have been merged with it by the power of this spell. The characters can travel back or forward up to one year per hour of casting time devoted in the casting. The casting time has to be continuous, and may not be interrupted. As the time a normal character can cast spells continuously isn't very long, this means that not too many years can be spanned with this spell. If one the other hand the character does not have to eat, drink or rest quite impressive times can be spanned.
The material components for this spell are:
•	one bone from every magically inclined race on the planet no matter how old - even if extinct;
•	the sacrifice of a fully charged staff of the magi which has to be broken apart (yes, roll for your survival, if you don't survive this the spell fails completely);
•	the creation of something utterly and completely new which has never been used or created before, costing no less than 1000 gp per year to be travelled in time (this item has to be useful and not complete bogus); and
•	the life of the caster (the caster is completely annihilated including body, soul and spirit, so that not even gods can resurrect or reincarnate him).
Thus, this spell is not cast very often by the same caster (actually, it is cast only once by a caster). And most casters are rather reluctant to cast it.
DMs: be careful with this spell. It gives your characters very much power, if they can think of the way to circumvent the last material component. They could create for themselves quite some fortresses, if they are smart, and they can defeat almost every opponent by going back in time to his birth and killing him then - or (much better) by turning them into an agent for themselves). So be careful who you allow this spell to have.
