Obviribdum

Obviribdum was a black-colored material. At some point by the time Kylo Ren, Supreme Leader of the First Order, had his shattered helmet reforged in 35 ABY, he had First Order technicians custom-design for him a reliquary case with an outer shell of reflective obviribdum in the shape of a truncated cube. The case was kept in Ren's private quarters aboard his flagship Star Destroyer Steadfast and contained the remains of the charred helmet of Ren's grandfather, Sith Lord Darth Vader. It was magnetically sealed, climate-controlled, and shielded from both radiation and sensor scans. Ren also had the outer shell of the case made blast-proof at great expense.
