Jason has turned into a Guardian, but his city is experiencing another crisis. A new and formidable enemy has appeared in the Twilight Throne, not at all afraid of Jason or other members of the Original Sin guild. To strengthen the city, it is necessary to take control of settlements located in the zone of influence of the Twilight Throne, find a source of replenishment of the city treasury and increase defense capability. The group gets to work and discovers, among other things, that the local zombie fauna is evolving in strange ways; it seems, under the influence of some unknown forces. One thing is clear: Jason has evolved, but his enemies are still breathing down his neck. The Twilight Throne will be able to survive unless Jason stops in his development and learns to properly manage his new skills. The price of a mistake is death...
