A couple months before the battle of Sigma Octanus IV, a portal is formed by some strange Forerunner device linking the Halo galaxy with the Star Wars galaxy a few months after the battle of Yavin 4. The portal opens in the Nal Hutta system (that is the name of the system to,right?) in the SW galaxy, and in the Halo galaxy above the Covenant colony world of Joyous Exultation. Can the Empire defeat the vast Covenant empire? Or shall human worlds and others in the Star Wars galaxy be glassed like the hundreds of UNSC space? Some quick facts about the Covenant. 1. They control a large area of the Orion Arm of the galaxy. 2. Weapons yields get into the TT range as shown during glassing operations in the book The Fall of Reach and First Strike. 3. The Covenant can afford to lose a of lot ships-nearly 1000 plus a mobile, 30km station in a two week period and not even make a small dent in their forces. 4. Covenant weapons range from 9+ light second ranges for Plasma Torpedos down to 10,000 km for all their weapons. 5. Slipspace is slower then then Hyperspace, but the Covenant can shall cross 25,000 light years within a one month time or so as seen in Halo 2. Slipspace drives allow the Covenant to avoid any sensors in normal space until they return to it, and pass through any real space objet such as stars, planets etc. without any effect. Also allows Covenant ships can make pin-point jumps with an error no greater then the diameter of an atom, which also gives them tac jumps. Say, Covenant ship is 10,000 in front of ISD-reappears behind ISD and turns it into swiss cheese.
