Disciples II: Dark Prophecy Windows, Linux game

In the beginning, there was nothing. The elder god Highfather had many angel servants, one of whom was his favorite - Bethrezen. The Highfather adored Bethrezen so much, the elder god granted him the power to create and left him to his own devices. Bethrezen, striving to impress the Highfather, created a new world and named it Nevendaar (also known as "Sacred Lands") in the angelic tongue. Once the world was complete, Bethrezen called on other gods to help him populate Nevendaar with living things. Gallean and Soloniele created the forests and the seas and populated them, besides wildlife, with elves and merfolk, respectively. Wotan created the dwarves on the mountains, only to have them dig back into the rock. Bethrezen created the humans. More gods came and created other minor races, but the main stage has been set. Bethrezen left to tell the Highfather of his creation, leaving other angels to watch over Nevendaar. Unfortunately, the angels resented Bethrezen being the favorite of the Highfather and decided to sabotage the new world. When the Highfather arrived to look upon Nevendaar, all he saw was war and destruction. Infuriated that Bethrezen would create such a world, the Highfather cast his favorite down into the core of his own creation for all eternity.

Ten thousand years have passed. Bethrezen, trapped inside the molten core of Nevendaar grew mad with anger and thirst for revenge at the Highfather and the creatures of the world. Unbeknownst to everyone else, he created a race of demons from the fiery lava of the core to be his army. Unable to escape his prison, Bethrezen sent forth his legions to destroy the humans, dwarves, elves, and all other living beings of Nevendaar. As it happens, the demons first struck in the elven lands, setting their forests ablaze. The elves panicked and fled their homes into the mountains of the Clans. The dwarves assumed the elves were invading and attacked the refugees. This prompted Gallean and Soloniele to demand that Wotan punish his children for the slaughter. Infuriated at their arrogance, Wotan killed Gallean and threw his heart into the sun. Soloniele jumped after it and managed to save it, but her own skin was burned away. Not only that, but she also changed inside. She found that she had the power to effortlessly kill entire peoples and then bring them back as her undead servants. Changing her name to Mortis, the fleshless goddess led her new undead minions on a crusade against the Mountain Clans to punish Wotan for killing her lover. Thus began the First Great War.
