Open the Gates of Warfang
The objective is to open the gates to pass this level. To open them you need to place the four crystal keys hidden throughout the level in the dragon statues sat in front of the gate. It is possible to go for keys 3 and 4 before 1 or 2 but it is easiest to follow the order here.
Crystal Key 1
Turn right and fly across the gap. Low down on a platform there is a spirit gem, you can see it shining through the fog. Smash this and then fly back up to the platform above. A small cutscene will show Spyro and Cynder looking at a carving of Malefor on the wall. Go along to the end of the platform and turn the wheel to lower a moveable wooden platform. Halfway during turning the wheeel you will be ambushed by skeletons. Dispatch them all and then complete turning the wheel to lower the platform. Fly out to it and have one dragon grab onto it, and then the other pull it back using the magic chain. It works in the same way as tghe boat did in the Valley of Avalar. Go back to the platform with the carving and grab on of the adamantite orbs. Use the platform to cross the gap
