abbaubar

Abbaubar is a fictional mineral that appears across science fiction literature, video games, and tabletop role-playing settings. It is typically described as a dense, iridescent ore with a glassy fracture and a color-shifting sheen that ranges from blue to green under different lighting. In many depictions, abbaubar forms as compact crystals or nodules and emits a faint glow in darkness.

The name is presented in-universe as derived from the Zephran language, with abba meaning light and ubar meaning binder or holder, giving a rough translation of "light-binder." The term is treated as a distinct mineral category within its fictional world.

Within its stories, abbaubar is described as exceptionally hard and dense, with a lattice structure that supports unusual electrical and magnetic properties. Some texts depict superconducting behavior at low temperatures, enabling efficient energy transfer, though these properties are described as variable and dependent on crystal form and impurities. The ore is often said to be brittle and challenging to extract without fragmentation.

Abbaubar is said to form in ultramafic rock environments, meteorites, or deep underground veins on planets with strong magnetic fields. In fiction, mining is conducted with advanced robotics and energy-manipulation tools, and the ore is considered highly valuable due to its rarity and potential technological uses.

Uses attributed to abbaubar in various works include power storage, magnetically levitated transport components, and ceremonial or symbolic objects. Its scarcity and versatile lore have made abbaubar a recurring plot element and trade good in several fictional economies.
