Strisath

Strisath is a Dragonkin that was shown in the final cutscene after completing the quest While Guthix Sleeps. It appears that he is planning something along with two fellow Dragonkin, Sithaph and Sakirth. little is known about Strisath or the other Dragonkin.

According to what was seen in the cutscene, it seems as if Strisath has gained great power from the Stone of Jas. Strisath's body was glowing brightly just like the Player's during the quest after you have made contact with the stone. Since the Dragonkin were forced to protect the Stone of Jas, It might be a clue that after the stone was stolen, the curse that was laid upon the Dragonkin had been released and they no longer are bound to protect it anymore which hints at their freedom.

Another theory is: Since the Dragonkin were forced to be guardians over the Stone of Jas, the cut-scene may be hinting that their power and duty to protect the Stone has returned. They also may be dragons later to be fought with. Since Lucien has stolen the Stone, the Dragonkin may be able to finally leave the fortress that they have been forced in for so long and are given free reins to do whatever it takes (with whatever power) to retrieve back the stone… They have been waiting for the Stone to be taken.
