The Patchwork are five beings made of metal, stone, and magic (among other miscellaneous materials) who take a humanoid shape. The way to create them has long been lost.
Initially, they were regarded by the world as curiosities despite their knowledge and understanding of the past, and they grew rather bitter and jaded with the people as generation after generation only regarded them as “Oh, look, it’s the weird metal people!”
Now that their knowledge is actually needed, though, they’re not exactly pleased. Now they’re important to the people, now they want to hear the Patchwork’s history.
They can even speak to the Giants. They can also fight, but, again, no one cared before.
They rely mostly on each other these days.
