The Chief of Tribe Thundersteel following the death of the Orcripper during the events of A Gathering Storm, and wielder of the Thunderhammer.
Hervok seemed rather hawkish towards non-Greenskin tribes and was something of a violent, selfish instigator. He was a tentative ally of Tribe Threefinger who helped him to win the civil war to become Chief of his clan until Zibrust was killed by Xil Wrenlow, after which he, as predicted by Moirin Mhic Macdha, made an attempt at a power-grab by stealing the Threefinger Spear off his corpse, killing Coldtooth in the process. He was kept at bay by Dimitra Adamos, Erastos Ironhoof and the Axemother before being incinerated by Wretch "Shadowborn", who took over as Chief of both tribes, and who took the Thunderhammer.
