Pertinax

Pertiax (Latin for Steadfast), also known as the Blank Slate Blade, is the second blade made by Marcurko, the opposite of Iaculis, his first blade. It was made to balance Iaculis' energy, as it threatened to destroy the universe. He sealed it away at the same time as Iaculis, but in a different place. It was drawn by Red Frost, Marcurko's descendant.
