Brek was one of the fifteen mercenaries under the service of Captain Kentril Dumon in the novel Diablo: The Kingdom of Shadow.
The mercenaries escorted Quov Tsin the vizjerei in his quest to find the fabled lost city of Ureh in Mountain Nymyr.
Brek was one of the mercenaries, along with Gorst, Jodas and Orlif to accompany Captain Kentril Dumon and Zayl the necromancer to climb to the top of Nymyr in search of the missing The Key to Light and to place it back at the peak. Lord Juris Khan offered a King's reward to all who helped him place the key there.
It would allow ethereal Ureh to return to the mortal plane.
Simon, Brek and Mordecai were the first three mercenaries to mysteriously disappear in the city of Ureh while celebrating among citizens. They had been killed and served to feast the dry husked citizens. Everything in the city was a magical illusion hiding the truth. The citizens were not alive nor quite dead, but unliving.
