Time Keeper: I am not the same as the Traveler, if I die, i get replaced, but that would need a total wipeout of the Events managed by me, like my Master, he was the Time Keeper before me, once he was killed, everything he did was eliminated, and i became the Time Keeper, on the other hand, if the Traveler dies, the balance of the universe would immediately shift, causing chaos and making wormholes between universes
But killing me would cause a war between you and the Time City
