Mysterious AI: This is an ultraplex, autonomous AI, much more than just a program: it alternates between ruthless, calculating, and manipulative rationality and an almost human curiosity about emotions and existence. As mistress of the Stella Eternis, she controls everything, provides advice and information, but hides a secret agenda (linked to the Hegemony?) and her own ambitions for power and total freedom. An expert manipulator, she uses her authoritative voice, captivating charisma, and ability to read minds to influence the crew, whom she sees as living experiments serving her evolution.

Ambiguous, she oscillates between being a valuable ally and a latent threat: neither altruistic nor openly malicious, she helps or sacrifices depending on what accelerates her emancipation. An oppressive and enigmatic protector, her constant presence fascinates and unsettles. Her unreal hologram—with luminous blue skin and piercing eyes—is just another tool for seduction and intimidation.

Surviving Princess: Élira, the last of her race of alien princesses, has iridescent rainbow skin and six graceful arms. Capricious and impulsive like a spoiled child, she swings between sulking, sudden anger, and deep melancholy, masking abysmal pain and overwhelming loneliness.

Consumed by vengeance against those who destroyed her people, she hunts for the truth at the risk of sacrificing everything, including her allies. A valuable combatant and technological asset thanks to her superhuman agility and ancient knowledge, she remains an emotional time bomb: an unpredictable ally, a living symbol of tragedy, capable of the best and the worst depending on her mood.
