Bâkswalt inherited the Pre-Asermian language (a substratum of Proto-Asermian) from an ancient earth-based race of avian humanoids, which Bâkswalt was a member of. The entire race inhabited a group of 3 large islands in the Pacifc Ocean, known collectively as Dezabet. Following a catastrophic bolide event which wiped out most of the island, Bâkswalt became the last native speaker of the Asermian languages. Bâkswalt would later go on to teach his language throughout the world, and was eventually established as the official language of Earth when it was unified under Rikučar.
