After the players located the Deck of Many Things they returned to Tyr. It had been around 2 months since they left the city and knew that an imminent attack from Urik was inevitable. When they returned they saw that the Urik forces had amassed miles away from the city. Tithian was not a full fledged Sorcerer King and his Templars were not equipped to deal with an assault from Urik's army.
The players defeated Urik's army. They went back to speak with Tithian to see what else they might do to make sure that the city was secure. News of Urik's defeat would surely reach the rest of the cities.
The players discussed the city's water reserves with Tithian and the city council. Since the Templars were dependent on Tithian granting their powers from him, the water supply was questionable. The players set out to secure a water supply from the Elemental plane of Water. They traveled down in the sewers to setup a portal when they discover a group of Caller in Darkness creatures. The players were able to dispatch them fairly quickly but not before on the Caller creature explaining to Sara that they were forced to seek out and create more undead victims. The group set out to see who was ordering them to create more undead minions. They travel to the Road of Crypts in UnderTyr and parlayed with an emissary that explained to them that they needed more undead recruits to help in the war between the Gray and Black planes.
