I thought of a modern-day world where people all over the world have different powers, and they are usually triggered by an extremely traumatic event (one of my main characters has an arsonist father and he burned their house down, killing his mother, and got jailed). The powers vary wildly and since it's a relatively new event and most people hide theirs, there are no studies done on it, therefore no official scientific explanation.
I literally thought about it like 10 minutes ago so it's waay underdeveloped but as a general idea, is it good?
