Four Quarians: Daro Xen, Rael ´Zorah, Kal Reegar and Prazza who want to start an expedition are surprised by a Geth ship. Just in time they were able to save themselves inside, the Geth followed them and they didn't come alone! Curious like the Quarian, they didn't just focus on defense. The beetles, crawling by the thousands behind a pane of glass, found them extremely interesting; they would have liked to take some with them while the Quarian looked at them and dragged enemies over the ceiling.
"Bosh'tet!"  The ammunition slowly ran out and they had to shoot as accurate as possible. They found some rockets in a box so that they could at least kill entire groups. They were determined that nobody should be left behind, everyone should get to the shuttle. You would want to be better prepared for the next expedition, but first of all it means to escape alive! "Keelah se'lai".
