Eisen looked at the shelf in front of him, trying to figure out which material he should best make use of for this project, the weapon of the Siren Prince. For jewelry, using aquamarine and pearls as the centerpieces seemed to be the best choice. They were deeply connected to the water element, so it would be easy to create proper improvements for the monster in question. That, and there happened to be some places around Asgard with large clams that they could source some high-quality pearls from, so Eisen had quite a few. Luckily, since the Siren Prince was quite large in size as well, he could basically just use the pearls and create scaled-up pearl jewelry that he would make with regular ones. He walked over toward the marble workstation, and started to carve into the flat marble plate.
