Myths of the White Lands Quest Guide
Head to Explorer Jack's house which is just north of the Lumbridge Castle grounds. Say that you'd like to try the quest, when he offers you the choice of doing the achievement diary, or the quest. He'll tell you about the Land of Snow, and how a snow imp came wandering in and told him a story. He told him a story of riches and wonders to behold. He wants you to go to the land of snow and bring back precious stones. Ask Explorer Jack how to get to the white lands, and he'll tell you the phrase which is "Ectosum glissendo".
Head west toward the wizard tower and go down into the basement.Talk to Isdior and he'll teleport you to the White lands. You'll then see the cave and see that the stones are in there. Now you must navigate your way around an ice sheet, which occasional rock proturding from the ground. Use these to help you stop.
You'll now be at the cave entrance, click to go inside. You come to another ice sheet with rocks, this time.
You'll then enter another room with the same thing, this time.
Once again you'll appear in an ice room, this time.
And yet again, another room, this time.
Almost done! This time...
For the last room, simply click East and you'll finnish the room. A cutscene will commence where you'll enter the room of a Yeti, and you must find a different way past. You'll appear back in the last room, this room has pushable blocks for you to help navigate yourself around. The idea is to get onto the north ledge so that you can enter the room that way.
Now that both blocks are in place, make your way out of the current room and into the previous one.
Once in the next room.
You'll now be up on the crevice. Enter to appear in the next room and make your way to the room with the yeti. Study the West wall, and an image will appear on your screen. This will activate the "Shout-in" option on the pipe. You'll then begin to shout, and the yeti will fall over. Head back the way you came along the crevice, and make your way back to the yeti room, and pick up the stones. Make your way out of the cave, and you'll see three snow imps.They'll explain to you that one of the Snow imps, named Marius, fooled Explorer Jack by saying that the stones are priceless when in fact these stones are nothing more but Yeti dung. Once the dung warms up it'll become very smelly, they want this to happen when Explorer Jack gets the dung. They will offer you to enchant the dung for you, allowing you to teleport with it and give it to Explorer Jack, after which it will start smelling. After the Snow imps have enchanted the dung, you can make your way back to Explorer Jack and hand it to him.
