Sealing of the Dark Titan

Era beginning/end

After bringing the Dark elves back from their sacrifice from an alternate timelines, slaying servants of the Dark One, and discovering the true name of the entity and its plans to corrupt the Archangel, the Heroes of the Dark Ages defeat the Dark One in an epic final battle. Though this does not permanently seal the fate of the titan. The Dark One's disciple, Er-Zul, steals the essence that imbues the Titan and binds it to a prison. There the Dark One is forgotten until the next age, acting only as a long distant memory of a nightmare that never truly ended.
