This series of caches are named after Ewoks. Ewoks are the teddy bear type characters first introduced in "Return of the Jedi"
Romba was the friend of the only Ewok casualty seen on-screen in Return of the Jedi. Romba was nearly blasted to pieces by an AT-AT. Upon recovering from the traumatic experience, he immediately checked on his fellow soldier and tried to wake him, to no avail. Romba's mind broke, and he stayed with the corpse of his former friend, mourning his loss in the middle of the carnage.
