how would a prince or bard of light operate? on one hand, they could use light to destroy, or "invite destruction through" light, but how about destroying light? would they literally cause misfortune to their group? or cause important information to be lost? is there a positive side to destroying light?

If I recall I’ve answered the Bard and/or Prince of Light, because I remember having mentioned how they’d literally be able to blind people by destroying Light. Causing a black-out, definitely destroying vital information, and causing misfortune by destroying luck. And, again, as I’ve mentioned with the Thief of Hope before- These more destructive powers are good to fight people. If you aim them at a baddy instead to your group, you’re fine. Otherwise you could see some piece of information that could breach the unity of the group, and destroy it- Sometimes the Truth hurts after all.
