The fun thing about Bardic muses in the NeXus universe is that they work exactly like a character in a musical who alters reality every time they sing. If NeXus was a musical, those mfers would be the most powerful people in that world.
Like let me just sit you down and explain the concept. Bardic muses get to use their magic through being the loudest in the room. If they can be heard then their magic can form, the longer they're allowed to perform or speak for, the stronger their magic gets.
If you let a bardic muse speak uninterrupted then they can use their magic, if you let them keep talking then they will fuck you up. IF YOU LET THEM SING A MUSICAL NUMBER? PRAY YOU ARE NOT THE TARGET THEY'RE AFTER. Pray that you are not alone in a room with a bardic muse who has enchanted speakers rigged in there.
The worst part is that they will get down to cupcakke and fuck you up at the same time, and that's lowkey iconic actually. But like imagine the shenanigans of an oldschool disney villain, but all the shit they make happen can actually kill you--AND THEY'RE DANCING WHILE THEY BEAT YOUR ASS TOO
