The Mogadorian Invasion of Lorien, known as the First Great Expansion by the Mogadorians, occurs 10 years before the events of I am Number Four. As the mogadorians continued to mistreat their planet and fail to do anything constructive about it before it was too late, they mounted an attack on the nearest planet Lorien, in order to steal their resources to replace their own supplies, which were very low or had run out.
The Lorien Elders, who are in charge of the defence of the planet, disappeared for an unknown reason. This gave the Mogadorians the perfect opportunity to surprise attack the planet. The first bombs dropped during a time of celebration on the planet where the Loric were enjoying fireworks and other festivities. While the bombs continued to drop, thousands of ships dropped from the skies dropping Mogadorian Soldiers and creatures off. The Loric were vastly outnumbered and soon, despite many fighting back, every man, woman, child and creature were slaughtered and the outer shell of the planet demolished.
The war began during the Quartermoon celebration on the planet. The first part of the attack consisted of bombing the planet with missiles and destroying several locations where lots of Loric were at that moment. Some of these locations include the Chimæra nightclub, the spires of Elkin, the Lorien defence academy and a Loric space station. It is also known that before the attack, the Mogadorians disabled the grid by shooting large violet beams of energy in the sky. Unknown to the loric at first, the beams were draining the grid's power systems so that the grid would not function on the day of the invasion. The reason that the Mogadorians could land so easily was because of the Loric; it was their own mistake. Since it was near the Quartermoon festival, the Loric believed that the violet beams were actually signs of the beginning of the Quartermoon but unbeknownst to them, it were signs to their doom. When the first missle barrage ended the Mogs landed a part of their ground troops and beasts on the service to begin the attack. Shortly after they landed a second wave of missles came this time targeted at high rises and apartments then even more ground troops touched down on the service. The Loric fought extremely bravely, bursting into flames, fire bolts of energy from their hands, creating storms, but hardly stood a chance because they were unprepared and caught completely by surprise. It took the Mogs 3 days to exterminate all life on the planet and at the end of the 3 days, they turned Lorien from a beautiful paradise into a wasteland. Two ships made it off the planet. The first held nine Cêpan, nine Garde, a Chimæra known as Hadley, and a pilot and the other carrying the final member of the Garde, Ella, her surrogate Cêpan, Crayton, as well as Lexa, Zophie, and many Chimæra. The Garde were destined to become the next generation of Elders and are hoped to return to Lorien one day and repopulate it.
Some of the Garde and Cêpan escaped on a ship to earth, each were assigned a number to be killed in and they could only be killed in this order
- Loric Race (excluding those escaped to Earth)
- Bolog Shu-Ra and other Mogadorian soldiers
