Here is the potential cast list, at least as a starting point. Each story will need at least two characters. Once a series is done, the cast will (potentially) be refreshed.
1) CARRIE WATERSON
Background: High School Girl, Senior Year (original character)
Powers: Temporal. She has an immunity to temporal paradox. She can also freeze people in place, push objects through short time intervals, wipe memories, and speed up or slow down time for herself.
Drawbacks: Once she sees an event, it tends to become a fixed point. Also, if she pushes herself too far, she can lose control and harm others around her.
2) MASON aka CHIEF
Background: Time Lord (Unisystem generation)
Powers: Temporal. His TARDIS tends to be in the form of a vehicle. His “Bardiche Zanber” acts as an all purpose “swiss army knife”.
Drawbacks: Not a fighter. Once a bit of a show-off, a more sobering incident in his past has made him reluctant to personally interact with other cultures, unless the situation really calls for it.
Background: Parabola, personified (original character)
Powers: Flight. Very good with calculations involving gravity.
Drawbacks: Can be overemotional, and whether her depression is at a maximum can be seen from her hairband.
4) ALISON VAN DER LAND
Background: About 30; living under an alias (Unisystem generation)
Powers: Teleporter. Range of about 16 km, able to carry no more than one person along. Cannot teleport blind, or risks ending up inside a solid object.
Drawbacks: On prescription medication for depression. Has her own moral code.
5) SIMON BLACK
Background: About 30 (original character)
Powers: None. Able to perform slight of hand.
Drawbacks: Dislikes technology.
