We know very little regarding the Calamity. Supposedly it comes from another world, it devours worlds and only you can defeat it. Unfortunately, it is all we know about it. Legends say it aims to return all life to the void, so maybe it comes from the void.

You are right regarding legends. I wish you best of luck in your endeavors, hopefully you will be more successful than us at finding the truth.

There are thirty-one of you. We expected you, but we didn't expect you to be that numerous. As for your final question, no, there are already a lot of you and I doubt any more heroes will arrive.
