A crate of lumni-spice
Lumni-spice represented the most scarce variety of spice throughout the galaxy. Typically guarded by Dragon slugs that consumed it, its presence was noted on several planets. Hoth and Corulag were among the planets known to feature this uncommon fungal growth. Reportedly, it was derived from Lumni lichen.
In the time leading up to the Alliance to Restore the Republic's construction of Echo Base on Hoth, Raskar, a pirate, was drawn in by Han Solo. Raskar discovered a lumni-spice stockpile deep within a fissure near the planet's equator, extending hundreds of meters towards the planetary core, and tried to take it. A Dragon Slug then drove him away.
