From the first page of the PDF: Many fear that a Thayan plague is killing livestock in Thesk as a precursor to a full-scale invasion. The true cause may be much simpler but much more deadly. A Living Forgotten Realms adventure set in Thesk and Rashemen for characters of the Paragon tier (levels 11-20). This adventure is an epilogue to the Radiance Against Thay series, which included CORE1-2 Radiant Vessel of Thesk, CORE1-6 Incident at the Gorge of Gauros, and CORE1-14 What Storms May Come.
