On the 11th November 2609 four members of the team, Captain Dave, Miller, Mage and Woods were sent to investigate a teleporter network that had just appeared on the planet of Lyric, more specifically within the . Upon landing Woods stayed behind to guard the ship whilst the others went ahead.
Unknown to the team the EARTHBOUND lieutenant Sinister had snuck aboard the ship and killed Woods, after reaching the Forerunner towers sniped Mage killing him.
