Zutotanium

Zutotanium was a rare metal from which filament parts used in Starfleet starship warp drives were made. In 2267, the USS Enterprise (NCC-1701) was exploring the Galaxy Zekbran when a mysterious force damaged one of its engines and burned out the replacement parts needed to repair it. The crew was forced to beam down to a nearby planet to find a source of zutotanium so they could make the required parts and repair the engine.
