"The mac cannons don't work on these guys. Royal personally tried to fight them but he didn't get very far before he had to retreat. The only way the dojo can be saved is if we find or forge a relic. Not just any relic, though, it has to be one that has the power to destroy even thought and the strength to withstand forces capable of destroying universes. All the current relics of this category are very far away, and we do not have the means of crafting one. Running away was the best option for the time being."
