"And so man, elf and orc alike were as close as kin, for they were brothers and sisters in chains. They were forced to construct Darkspires, unholy towers that sate the Daemons' colossal appetite for reverence." ~ Arondil Jalthirys, The Daemon Chronicles
Darkspires are un-worldly towers that can be used to summon Daemons. They also serve as temples, with worshippers empowering the Daemonic race. A whole host used to exist all over Valedonia during the Daemonic era, in which all races were enslaved and forced to construct such towers. All known ones were destroyed, although some rumour that the remnants of the Darkclaw Brotherhood are rebuilding a Darkspire.
