So, reading grim vol 3, got a real stupid idea, anyways. We see in a few cutscenes, those first scientists who visited the traveler on Mars got light abilities though not guardians (theory 1): these were the first official light bearers yet hid it, or bungie was just making those cutscenes for no reason. We also know there were four people on the Artemis 1 mission, although one died. (Theory 2): three scientists met the traveler, traveler made 3 guardian classes. Sooo for the sake of appeasing the random tangent I’ve brought, what if the 4th scientist lived? Could there have been a 4th class? Utter idiocy, I know
