- "The ore barons have forged and hardened phrik for bones. We build palaces where others would struggle to even mine."
- ―Baron Rubix
Phrik was a metallic compound that was nearly indestructible. Phrik was mined on Gromas, in the Perkell sector. Darth Sidious's lightsabers, created by Darth Sidious during his apprenticeship under Darth Plagueis, were made from phrik. Electrostaffs built by the Baktoid Armor Workshop were also made of this material.
