Kill Hard-Heart

Quest Giver	Percius Mercius in Ald-ruhn
Prerequisite Quest	Remove Sjoring's Supporters
Reward	Promotion to Master

After you've killed Lorbumol gro-Aglakh and (possibly) Eydis Fire-Eye, Percius Mercius in the Ald-ruhn, Guild of Fighters will ask you to kill Sjoring Hard-Heart in the Vivec, Guild of Fighters next. Evidently Hard-Heart is the heart of the Camonna Tong influence in the Guild. Percius also gives you use of his personal chamber in the Ald'ruhn Fighters Guild, complete with an almost full set of Orcish and Glass armor among other equipment to use (or sell).
