Originally a vassal to Hrawoao clan, Hlyueawi rose to
power during the Yerlyaruiwo-Tralyeaeawi
War. Members of Hlyueawi were renowned experts in strategy and political
science, a few of whom produced classical and widely read treatises on these
subjects. The clan regularly provided advisors to the rest of the Yerlyaruiwo
bloc. But during the growing instability of the Yerlyaruiwo-Tralyeaeawi War,
Hlyueawi struck out on its own.
Through clever planning, the HIyueawi arranged the fall of Uawairlew, a major clan also of the Yerlyaruiwo bloc, in 6060 (652 Imperial). It took over most Uawairlew assets, and replaced that clan on the seat among the 29. Hlyueawi quickly sided with the Isoitiyro to consolidate itself, quickly gaining a respectable ranking.
