For the people who have done the 1st Grandmasterquest, When guthix sleeps, a small spoiler has been released on what would be the subject of the next Grandmasterquest, as when you've completed the quest you get a cutscene of 3 dragonkin monsters in deep wild talking about their evil plans. When I saw the cutscene, I felt like the dragonkin specie wasnt new to me, but forgot about it untill today. I was questing a bit on my pure account, and all of a sudden I found out where I heard of the Dragonkin before! During the "A tail of 2 cats" quest, the dragonkin gets mentioned in the legend of Robert the Strong aka Bob. Most likely Bob will be a huge factor in the new quest, so for when it gets out, maybe it'd be wise to get your catspeak amulets out?
