For many years the battle between aliance and horde devastates the four corners of Azeroth. In the constant search for more allys, each faction fiercely attempts to destroy their enemies without paying any attention to the surrouding enviroment. If the coming of the Burning Legion wasn't enough for the land, both factions have been deforesting entire landscapes to strenghthen their armies with weapons and shields, dried rivers with thrist from resting troops, killed living beings only for the lusts of blood and poluted the air with their machines and inventions.
Some elder Gods decide to mold a group to be the perfect army, to use all their habilities towards the victory of the Horde. From diferent locations of Azeroth, with diferent ways, the Gods guide their chosen ones to meet one another, so they can meet and together form the Perfect Army which would be known as the House of Seven Sins.
While each leader from the Horde built their bases for the next battle, an unidentified prophet shared a vision with the leader of orcs and trolls, Thrall. This vision showed him the destruction of Azeroth in case the rapid destruction of the land wasn't dealt with, the prophet also showed Thrall old artifacts with enchanted inscriptions. The profecy and the artifacts were unknown to Thrall, but inspired the elader feelings of truthness.
The prophet asked the leader to summon a troll warrior with healing habilities to host the first meeting of the House of Seven Sins, and lead the group's first trainings and missions. Thrall consulted Vol'jin, his trusted counselor, who sends forth a messenge to ParanoicO, a prominent priest, to reception and begin training the incoming soldiers from diferent parts of Azeroth.
The prophet didin't give much explanation why the groups name should be House of Seven Sins or what they'll be fighting against, but guaranteed to return for further instructions. The first task was to gather the group as quick as possible on the simple Jaggedswine Farm, located approximately 150 yards south of Ogrimar, where they would wait for further orders.
