The Grey Heart

A small blob of nano technology is summoned into one of the worlds of Allfoordrasill in a attempt to bring in technology to prevent a looming apocalypse, after an accident it is launched into the wild, without instruction it begins to create its own... I intend this story to be a power fantasy, but not to a ridiculous degree, the main character will become stronger, and eventually extremely strong, but I won't pull any "ah I see how the magic works, so I will simple program it into myself and become the greatest mage in ~2mins" I intend for the nanomachines not to be magic, they will obey most of the laws of physics, which means that they cannot simple consume any material to replicate, and they are made of normal materials, and thus aren't impossible durable, computing power is needed to control them, they need to be occasionally charged, etc. I am writing this story because I want to, but I am in university, and thus might not be able to upload consistently. Just a heads up. Also, I am a fan of the Youtube channel Hogfell and give permission for my story to be used by them.
