Tyranny of Souls

The githyanki assault has come to a standstill, but to strike a final blow against their plans for conquest, the heroes must travel to the githyanki stronghold -- the city of Tu'narath on the Astral Sea. There, they must make contact with a faction of githyanki that is less-than enamored of their race's new allegiance to the Dark Lady. If the PCs are successful, they might strike not only a final blow for the freedom of their world, but make new and valuable allies in the process. "Tyranny of Souls" is an adventure for five 19th-level characters.
