A certain being was an inhabitant of the seas found on the world of Mon Cala. In the course of the Battle of Dac City, Lee-Char, the ruler, made use of a pair of these beings; they leaped out of the water, then plunged back in, generating a massive wave that obliterated Dac City. Comparable events unfolded across the entire planet, leading to the total ruin of every city on the surface, and obligating the Galactic Empire to depend on aerial landing platforms.
