Hi! please can someone tell me who are the heroes in that expansion?

Banners of War?

There are 8 new heroes: Andira Runehand, Grey Ker, Ispher, Landrec the Wise, Lyssa of the East, Steelhornes, Trenloe the Strong, and Vyrah the Falconer. (Basically, the same heroes that were in the Island of Dread Runebound expansion, and the 8 additional heroes that were in the Descent base game that weren't already in Runewars).

Thank you very much sigma!
