Relative siblings

Ajax just died, to discover he has time powers, yay! The powers just have one, okay that's a lie, a lot of problems- like him still being on the freeway, oh also apparently his use of magic has awakened magic for the rest of the universe.

Ajax has the power to travel to any time in his life he remembers, and his sister Saira has the power to teleport to any place she remembers. Join these two siblings as they discover and abuse their powers, while handling the consequences of their actions, either the rest of humanity hunting them or the apocalypse they are hunting them for starting.
