Meet me in Taverly. I will explain more
In Yubiusk, visit the giant box thingy. Oldak will utilize a slayer gem with it, and RuneScape Mobile gold also an ethereal Zanik will look. Whu...? [insert name here]! How did you. . Zanik, where are you? How can you get ghostly? Are you dead? No, I understand that. I'm trapped in some kind of dimension. Bandos is trying to kill me I think. Why has not he succeeded?
That would be my doing. I'm Sanfew. Wait, you know me, I'm [insert title here] oh hello. I'm not, I'm only here in astral form. No. I am able to shield your friend from Bandos' anger, however I can't free her. Perhaps you can. You will need to break open this thing though, then you would need to drive her out.
Sanfew: Well, I'm not sure how you would start the sarcophogas. Only the elite Bandos followers may do that. But to force your buddy out, you could discover an object of hers, take it to an obelisk and create a summoning pouch of her. Then you merely summon her. Oh, and you're going to need to provide her a special potion so that she will not only disappear after a few minutes. I am confused.
Meet me in Taverly. I will explain more. Proceed to Taverly and inquire Sanfew about your experience with him. He'll explain that to ultimately free Zanik, you must open the box item, summon her using a pouch, then use a potion on her she doesn't evaporate like nearly all of cheap OSRS gold your other familiars.
