Kavash shows the Shard-seeker how to light Ytar's flames
Kavash, together with Esil, were friends of Shura. They were among the volunteers that followed Shura into the Misty Valley[1], but along with Kavash and other Monks were separated from the larger group by the Black Mists and became stranded in the Silent Monastery.
The group was attacked by Nightmares, but they managed to escape deeper into the monastery. Unfortunately, they encountered the Guardian of the Nightmare who proceeded to slaughter most of the group.
The Guardian spared two Monks to be sacrificed to its master. Just as it finished with the sacrifice, the Shard-seeker arrived and drove it away[2].
Kavash was grievously injured and clinging to life. Before he passed away, he taught his savior how to use Ytar's flames weaken Nightmares[2].
