[i]You're referring to Darth Nihilus, aren't you? That guy had to be in orbit of a planet to drain it's life. Never once did he do it from a star system away. His power, just like all Force-powers, only work on beings with connection to the Force. The Force does not exist in Halo, as it's a separate universe with a different set of rules. Nihilus is just another guy with a lightsaber to Halo standards. The single greatest destructive feat in all of Star Wars is the ability to destroy a star. The Sun Crusher was the only one of its kind, and it was the only weapon capable of blowing up stars. The Forerunners blow up stars for fun. Superweapons in Star Wars are common practice for the Forerunners. The Forerunners solo all of Star Wars, and that's without bringing in the UNSC, the Covenant, the Flood, Ancient Humanity, and the Precursors. [/i]
