Slogg-Nhumazdar was a wealthy and ambitious trader that arrived in Zamora in the city of Zemizar around the time Conan of Cimmeria was still in his early adventuring days. It was at this time that Slogg had intended to monopolize on the slaughter house industry of the city. He used a small army of mercenaries to drive off his competitors, and raze their establishments.

Pretending fealty to Sahb Delanzar, Slogg entered into a partnership with the Brotherhood in order to take over Zemizar's slaughter houses.

For a time, Zemizar prospered as the meat trade in Zamora was controlled by the Brotherhood of Sahb Delanzar, but administered by Slogg. Both became wealthier than they already were from this arrangement.

Soon afterwards, the various Zamoran kings conspired against Slogg and the Brotherhood, choking off their trade with military and economic sanctions. In order to maintain his lavish lifestyle, Slogg began selling goat meat out of his slaughter houses. The goat, however, is the most sacred of all animals to the Brotherhood, and this caused tension between the two trade partners.

Ultimately, conflict erupted between the two factions as servants of the Brotherhood struck at Slogg's slaughter houses, burning them to the ground. Slogg retaliated by attacking their temples and killing their followers. Ultimately, armed confrontations began to take place between the mercenaries hired by Slogg, and the religious warriors devoted to their Goat God.

The war between the two went on for over a year, but gradually the Brotherhood began gaining the advantage.

In an effort to salvage his holdings, Slogg offered a truce to the Brotherhood; all hostilities would cease so long as Slogg would no longer sell the flesh of goats, and as a symbol of their new pact, Slogg would marry Lissandra, the daughter of the High Priest of the Brotherhood.

They married, and soon after, Lissandra had given birth to a son.

For a time, things went well. The fighting had ended, and both the temples and the slaughter houses resumed operations, until Slogg resumed the slaughtering of goats again. Knowing this would invoke their displeasure, Slogg took on more mercenaries; among their ranks was Conan, a Cimmerian. In their anger the Brotherhood began to attack Slogg directly; sending assassins to his home to kill him while he slept in his bed, but were thwarted by Conan.

What neither Conan or Slogg could know was Lissandra was secretly conspiring against the pair, while feigning the doting and loyal wife.

Upon discovering that the Goat God, Sahb Delanzar "The God of a Thousand Young" demanded the sacrifice of infants who he would then one day lead in a bloody crusade to consume the earth, Conan rushed back to warn Slogg, only for the pair to discover Lissandra and a priest of the Brotherhood absconding with their infant child.

Slogg killed the priest, but his wife escaped into a hidden tunnel with a fellow cultist and the baby. Slogg along with Conan and a group of armed men pursued them, and were met by a group of reanimated corpses brought back by the Brotherhood's blood magic. After a brief battle in the tunnels, only Slogg and Conan remained.

At the tunnel's end they came upon the Temple of Sahb Delanzar, with Lissandra dressed in the garb of a High priestess, her own child on a sacrificial altar prepared to be offered up to the Goat God. Slogg and Conan fought their way through the throng of cultists to stop the sacrifice, but Lissandra used her own blood to summon the dread Goat God.

Slogg, in an effort to save his own life, offered up his son to the looming god given form, but Sahb Delanzar, grabbed both Slogg and Lissandra instead, killing them both in his giant hands. Conan, realizing the blood-stained talisman used to summon the Goat God was the source of his power, shattered it, sending the Goat God back to his hellish nether realm.

Conan took Slogg and Lissandra's infant child and gave him to a villager several leagues from Zemizar, who graciously took him in and promised she would raise him as if he were his own.
