Covenant

London, 2038. Man became dependent on science, believed only what he could define or create. Ancient knowledge and rituals were lost. Prophecies ignored. So when the harbingers of evil began to manifest, few saw and fewer believed. So when the demons came there was little to stand in their way. Emerging from the swirling chaotic Hellgate, they overwhelmed humanity's defenses. The usual tactics of war were useless against them - only the few who still respected the old ways, with their holy, ancient and arcane rights could stand against the dark invaders, using weapons and spells forged in the traditions of their forefathers. But their scattered sucesses attracted vastly powerful enemies, forcing the survivors of London deep into the relative saftey of the Underground.
