Third Sapa Inca; son of Sinchi Roca by Mama Cahua-Pata of the Oma lineage. Quartigod by registry math (Sinchi Roca demigod 0.5 + mortal mother 0 → f=0.25 = quartigod). His regnal name encodes a personal trait (left-handedness, lluq'i) elevated to dynastic-honorific status, illustrating the imperial-Inca convention of name-as-attribute that produced the distinctive Sapa Inca naming-pattern. The Auaynin Panaca founded by him maintained corporate identity through the conquest. Conventional dating c. 1260 CE, legendary-historical rather than archaeologically anchored.
