You may go up to 10,000 years in the future or past/ level. You may do this once every 30 days.
You may carry anything you touch directly or indirectly (i.e. if all your team mates are touching someone who is touching someone who is touching someone...who is touching you, your whole team may time travel.)
If you kill or prevent anything from dying in the past or the future there will be consequences. This could be something as different as the Nazis winning World War IV, to the telephone being called the tagomat, to the end of existance. Given these variations do not attempt to mess with time because Father Time will get peaved and you don't want that.
