Tiny, detailed, fiddly work is Loki’s specialty. It has always been so, ever since Thor was out tussling with his friends or hunting down bilgesnipes at far too young an age to be off by himself and it was up to Loki to carefully sew his injuries shut. As he grew older and became more learned, his steady hands became even more of an asset, assisting the healers in their work or collecting and preparing ingredients for his own personal studies. He is, to the best of his knowledge, the only seidr-worker to extract the venom from Nidhogg as he crouched chewing on Yggdrasil’s roots and survived.
Needless to say, he is very proud of his ability to be patient in the face of tricky, delicate work. This fragile piece of Stark-glass, however? That patience is sorely tested.
