The Dao are powerful beings hailing from the elemental Unknown. Thousands of years ago, during the tumultuous period known as the Earthen Wars, The Earth Realm faced a grave crisis. Seeking to preserve the delicate balance between the underworld and the overworld, the Dao struck a momentous deal with Avatar Umber, the enigmatic ruler of the Earth Kingdom. Under this historic agreement, the Dao agreed to separate The Underland City of the Dao from the rest of the realm, ensuring peace and harmony between the two realms. Masters of earth and stone, the Dao command the mighty Xorn to tunnel out a sprawling city beneath the earth, constructing the magnificent Underland City that stands to this day.
The Dao's complex nature embodies a paradoxical blend of malevolence and honor. While they are known for their inclination towards enslavement and domination, they also hold a deep-rooted fear of losing their freedom. Despite these seemingly conflicting traits, the Dao is not devoid of appreciation for acts of fairness and kindness, often returning the favor with a sense of reciprocity. Renowned for their craftsmanship and meticulousness, the Dao take immense pride in creating well-made objects and devising cunning plots. Their affinity for precision makes them formidable adversaries, a force to be reckoned with in the ever-shifting landscape of Osira. Thus, the Dao's history, forged through a pivotal deal with Avatar Umber, and their remarkable ability to command the earth beneath them grants them a significant and intriguing role in the intricate tapestry of Osira's history and lore.
