Battle of Helska
this was the term used by historians to describe the New Republic's first victory against the Yuuzhan Vong. The alien invaders had placed an immense yammosk deep within Helska's core, hoping to grow it as the basis for their initial strikes against the Republic. In a daring series of missions, the Republic forced the world to warm and then re-solidify via the Mezzicanley Wave effect. Helska's matter was unable to handle the strain of the effect, and shattered into a billion pieces of ice and rock.
