The Saienca language of the Saenoch, as a spoken language, is said to predate their discovery written script and Caretaker language by centuries. Instead, their culture relied on a complex oral tradition of stories and poetic epics to record history. Perhaps because of this, the Siaenca language seems to have a poetic cadence to it, and seems to rely heavily on rhyme and meter.

Siaenca is primarily spoken by the Saenoch and typically amongst only their direct family. The language is rarely taught to outsiders, and because of this Siaenca is not particularly commonly encountered in the Shards.

The modern script for Siaenca was only developed in the past few centuries after encounters with Caretaker ruins. Adapted for wood carved tablets initially, Siaenca takes on a very etched, runic structure - but otherwise conforms fairly well to the typical Caretaker script structures.
