This spell enables you to travel in time to the future only. This spell does not enable you to travel to the past. This means it is a one-way trip.
You draw on the ground a circle of sigils with a diameter of 10ft, placing the material components and the objects or creatures you want to send to another time in the circle, and within a height of 10ft from the floor (a cylinder). Once the casting time is finished, you touch the edge of the circle, the material components are instantly consumed, and you unleash an unimaginable amount of magical energy into the cylinder, which teleports those inside, and the air around them, to a time of your choosing (you can be in the circle as well). A thin slice of the floor will be transported, but not the sigils. A Thunderwave blast will be followed by a strong suction wind as air rushes in to fill the vacuum. The destination time can be no further than 5,000 years into the future. The physical location of arrival can be anywhere you decide in the material plane. The time travellers will instantaneously be transported, and will only notice a flash of light and a sudden change of scenery. At the destination, strong winds will erupt away from the time travellers as they appear and air is displaced. If the destination area is occupied, the cylinder will be moved to the closest available free space. Casting the spell is an ordeal, and has a 50% chance of instantly killing and disintegrating the caster. If multiple mages assist in the casting, this risk is reduced by half for each extra caster, with 3 extra casters being the recommended number.
The Effects of Time Jump:
Time travel to the future is simple in comparison to travel to the past. The target simply vanishes from existence, and reappears after a long time has passed. They might find the world of the future very different from the world they left behind, due to changes that occurred during history. The spell is extremely difficult and secret, because it could potentially be a potent weapon in terms of removing other creatures or important items from the universe for thousands of years.
