Colloquially referred to as 'the gray wastes', Urakh is the destination of the principally apathetic in batarian eschatology.
Like most cultures, batarian mythology presumes the existence of multiple realms of the afterlife, to which a person goes after death depending on their behavior in life. However, their equivalents of the Abrahamic 'heaven' and 'hell' are different only in the kind of person who inhabits them, essentially making each a paradise for its inhabitants based on their desires and impulses. Those unfortunate souls who, in life, failed to commit themselves to a set of principles find themselves in Urakh, which is described mostly as a silent, colorless wasteland whose depressive qualities are only matched by the sheer amount of boredom the region engenders. In keeping with the 'go big or go home' nature of batarian society, this is seen as a fitting punishment for apathy and failure to support a cause or leader. Individuals who die without their eyes are also cast into Urakh; since the soul can only exit through the eyes, it is rendered unidentifiable and cannot be judged, which lands it in the gray wastes by default.
Although the Batarian Hegemony was a secular government and didn't encourage belief in its ancestral mythology, the concept of Urakh as the ultimate disgrace still exists in batarian parlance, as a form of generational culture osmosis, and is often used as a socially-acceptable profanity.
