The Rakshasa Kashtarhak is a prakhatu, the chosen servant of the Overlord Eldrantulku. The prophecies of Ashtakala say that Eldrantulku will rise again when a mighty empire tears itself apart from within. Kashtarhak helped institgate the elven uprising in ancient Xen'drik, and played a part in shattering the Empire of Dhakaan. Now he whispers in the shadows of Khorvaire, hoping to bring down the last remnants of Galifar. His fangs encourage anti-monarchy groups and those who wish to see the war begin anew.
