The Order of Zakarum is one of the religions devoted to the Light, but due to corruption, it became instrumental in the resurrection of the Prime Evils. It is possibly based on the Catholic Church of the 15th century.
In ages past, the Archangel Yaerius visited a young ascetic named Akarat and revealed to him the tenets of what was to become the religion of Zakarum. These teachings stressed the necessity of resisting all things evil, and embracing, with total devotion, the Light. The angel appointed Akarat to be the prophet of these new teachings, and bade him take the word to the people of all lands. This new religion spoke directly to the common man, and the people of Kurast embraced it. They sent disciples throughout Kehjistan to spread the word. Popular religious leaders soon sprung up, endorsed by the new church, and within half a century Zakarum was the dominant order of faith and binding political force in the East.
The Zakarum are based at the city of Travincal in Kurast. Their ruling council, the High Council of Zakarum, rules from the majestic Temple of Light in the middle of Travincal. The Zakarum is ruled by the Que-Hegan, a godly figure similar to the real world Pope.
The Zakarumite Holy Army is composed of a complex hierarchy of many levels. The highest being the Que-Hegan and his seven Archbishops. Scores of Paladins and Knights form the lower ranks.
Following the capture of Mephisto, his Soulstone was buried deep beneath the Temple of Light. There, Mephisto spread his influence all over the Zakarum ranks. He forced them to create the Compelling Orb, with which he spread his influence all over Kurast. The only one to resist his corruption was the contemporary Que-Hegan, Khalim. Mephisto therefore ordered his followers to brutally murder Khalim, dismembering him and scattering his parts all over Kurast.
Mephisto then ordered the High Council to shatter his Soulstone. Six shards of the Soulstone were driven into the left palms of the High Council Priests. The seventh and largest shard was driven into Sankekur, who would become the living embodiment of Mephisto, warped into an approximation of his master's true visage. Mephisto used his newfound followers to procure him power and nourishment in the form of human sacrifices.
Soon, Mephisto sent his favoured lackey, Archbishop Lazarus, to the forests of Westmarch in order to free Diablo in Tristram. The Temple of Zakarum lost its former glory and the Temple of Light was soon renamed the Blackened Temple. Hordes of fanatic Zakarumites still run havoc in the once glittering streets of Travincal, terrorizing the natives.
Diablo 3 Edit
In Diablo 3, the Order of Zakarum still exists, however its order is known as the Templars. the Diablo 3 Journal "On the Desolate Sands, Part 3", refers to a member of the order, Brast, who is a Zakarum scholar. Kormac, the templar follower, often mentions this member of the Templars.
