Time Gauntlet

The Time Gauntlet is a wrist-mounted device developed by the Interstellar Manufacturing Corperation and recovered by the Frontier Militia. From here it was replicated and became a more common item.

When used, the Gauntlet allows the user to travel between two timestreams; the present and the past. When transitioning the two timestreams, the stream being "exited" is effectively paused and the stream being "entered" is resumed. Additionally, objects transitioning between timestreams retain their geographic position in relation to the planet they are on (despite the movement of celestial bodies in their orbits), momentum and velocity. This results in users of the Gauntlet being able to, for example, sprint and jump off a ledge in one timestream and then land on a platform that was previously nonexistent in the other timeframe.

4 Times per Long Rest, the wielder may travel forwards or backwards in time at a distance of 10 years, allowing them to explore a point in time freely.
