Long before he achieved High Ranker notoriety and founded Wolhaiksong, Urek Mazino breached the massive gates of the Tower as an unyielding Irregular. Unlike ordinary Regulars who climb to fulfill royal contracts, claim riches, or ascend social castes under Zahard's empire, Urek entered the structure with a singular pursuit: chasing the supreme existence known as Phantaminum. Cast into initial Floor evaluations alongside ruthless candidates and calculating Test Administrators, Urek instantly disrupts established hierarchies. His body moves faster than Shinsu reinforcement can anticipate, and his uninhibited strikes demolish barriers meant to test full teams of climbers.

The narrative tracks Urek's early ascendance through the gauntlet of survival battle royales, corporate syndicates, and Ten Great Family scions attempting to exploit or eliminate him. Rather than bowing to tests administered by Floor Rulers, Urek challenges administrative authority directly. His carefree persona contrasts sharply with the grim, predatory politics of the Tower, revealing the origins of his personal philosophy regarding genuine freedom outside the sealed structure. Every floor traversed forces ancient powers to acknowledge an Irregular whose growth defies measurement, setting the stage for the legends that later defined an era.

What to Expect
