Ishfa

Ishfa
The Ishfa were a species of metaphysical beings that invented Allionics and were servants of the Three Titans of Power. They looked like wispy humanoid creatures but with no legs, instead a single tail-like extremity replacing them. They were also an ethereal blue colour. Their origins are unknown, the most that is known about them is that sometime a long time ago, while serving Leonne, they gained access to the Book of Time, which records all the events in the current timeline, past present and future. They read it and used the knowledge to help other civilizations. Leonne took away their souls for attempting to warn other species about future events, betraying their loyalty to Leonne. Because their souls were removed, their delicate metaphysical bodies could no longer hold themselves together, and they needed souls or risk dying out. They quickly searched the galaxy for another race that had souls and found the Terrans. Specifically, mankind. Only the strongest Ishfas survived the journey, and when they bonded with the humans, they created the Ultimates. But with this, the Ishfa died out for good. The Ishfas personality blended with their host's personality, and so did their bodies. And when the Ultimate's appearance became almost 100% human-like, the Ishfa became truly extinct.
