Ulterian is the written and spoken language of the elders.
It is considered a dead language today. It gradually disappeared after the Prescient Empire formally banned it under penalty of death, imposing a single language: Nullian.
Mysteries surround Ulterian. Some claim Ultera herself offered it to the first human; others believe it was brought from beyond the stars—built upon complex, cryptographic structure.
Rare inscriptions can still be found while exploring Ultera, but translating them is often risky.
