Ren's powers aren't the most conducive to this sort of thing, but he might suggest that the natives at least attempt using the glow's powers against it to see if it cancels out somehow. He's probably not going to be too eager to use his own powers near the hole until he's more sure of what's likely to happen if he tries (though if literally nobody else wants to then he'll step up), but if anyone else wants to attempt attacking it then he'll support it.
