Copper

One day, he received a suspiciously well paying job inquiry (80,000 treasure! For some flowers, outrageous!) requiring him to acquire ink. Red ink. An oddly specific shade of red ink. A little more research into the ink said that it only came from redblood snappers in the Mire. These plants were commonly dropped by those damn cats from hell- Scythe Kamaitachis.

In a pinch for treasure, he took up the job thinking it'd be a one time deal. A couple weeks after he'd sent the flowers out to his employer- who went as Starfall- he received another letter. Same person, same job, same paper even, but most importantly the same high payment. There was a little add on at the bottom though,

If you'd be interested, this offer could be a steady job. Write me back asap when you decide.

Also his wife Essa was sent off and died whoops

...we don't talk about his ugly tert either
