You decide to get the cadava berries first. You south of Varrock and see a large stone circle with a bunch of dark wizards in it. One of them talks to you. "Hey, are you Susie?" "Yes." You say "The powerful Zamorakian mage, Susie?" "Are there any other Susies?" "Good. You see here, we're trying to summon the great demon, Delrith. It would mean a lot to us if you helped."
