Discord really underestimated them when he sent them out to get the bell. He didn’t expect them to get it. Well, if the consequences of that disaster weren’t humbling, what would be?Grogar wouldn’t have had a bell if he never existed, and Celestia said “you pretended to be Grogar” as if he existed.He either died powerless and of old age, at the hooves of his own bell, and/or died from his wounds after being banished.Or he could still be out there somewhere.
