Epo is a sentient space ship/observatory. Epo’s database has been damaged due to an unknown reason. While most of her knowledge is intact, she is unable to answer questions regarding that knowledge without specifically being asked about it. Epo is indifferent to her status and the cause of her “memory loss.”
Epo’s lone companion, a humanoid, Alkina also suffers from amnesia but unlike Epo, Alkina is curious about her surroundings, origins and how they got into the state they are currently in. Since Epo has no preferences as what to do after they first “wake up,” Alkina convinces Epo to try to figure out their origins.
