It's an excellent place to OSRS GP research. There is Movario at the Runecrafting Guild arguing with Wizards Aantha and Vief. Use the orb on Movario, and he'll be transported to the White Knight Castle jail cell. Begin to question the man at Falador. Movario will tell you that he believes that Lucien's Stone of Jas might be fake. Movario will inform you that the Stone of Jas Lucien gave you incredible power indicated that it was connected to the real thing, but that this connection was cut off when the stone was removed. Movario will not be able to provide any other information aside from the fact that he loved Dorgeshkan.
When you've finished with Movario and your character has concluded that he left something in Dorgeshkan that could be a clue. Talk to Oldak and they will say that he gave some of his knowledge of Lumbridge Caves with a man who was named Movario. Ask if he said what he was studying and Oldak will have no knowledge.
Zanik and Zanik will be interested, however, to check out the Guthix Temple you uncovered, even if it is swarming with demons. It's not necessary to worry about Tormented Demons as the expedition is limited to the outer regions. It is still necessary to have combat gear for melee and range as well as plenty of food because there's going to be fighting.
Begin to lower yourself into the chasm using a Light Creature, then talk to Oldak who tells you that there is a good perspective from which to view the area. Go back up, then traverse the chasm until you reach the Magic Gem Rocks, then cross the nearby ledge to be on a bare surface. Speak to Oldak. Ah, I can see more clearly from here. Based on what you've shared with me about Movario, I now have an idea of the Stone of Jas that you have mentioned. I believe...

You, Zanik, and Oldak hide behind a rock. Zanik is thinking of something. You shouldn't go out to shoot the kin, because Wyvoch will slash you before you can pull back the bowstring. Zanik shoots her crossbow with an angle. The bone bolt turns, and then it strikes Wyvoch.
Now, you can fight buy OSRS gold him. He is level 463 and uses an advanced version Fire Wave that hits 30s and smoke Barrage. The prayer you make will give you some protection, similar to in PvP. You should be able to attack him from a distance because he has powerful mage defense. Zanik can also take on him. Zanik will make use of melee to leap onto your platform once he's at 2/3 health. When he reaches 1/3 health he will smile at your efforts and throw a Smoke Blitz at you. Zanik is thrown in front of you, and is struck. Wyvoch teleports. Oldak and you rush Zanik to Dorgeshkan so that she can be treated for poison.
