Your ancestors remained in the Scoured Stars System on their home planet of Agillae-4 when most izalguuns fled. Those who stayed behind had to abandon their major settlements, which fell into ruin as the survivors took up a nomadic lifestyle, scavenging technology from the remains of their previous civilization. You're accustomed to working with technology without having the proper tools. You become trained in
Computers. If you would automatically become trained in Computers (from your background or class, for example), you instead become trained in another skill of your choice. You don't need a
hacking toolkit to interface with a computer to perform the
Hack action, instead making do with whatever tools are at hand. You also gain the Undo, Undo! reaction.
