The Gates of Cauldron Hollow  

This quest is given by Arqis in Nektulos. He is located near the bridge to Commonlands. Completing it gives you access to the raid zone: Cauldron Hollow.

The first order of duty is to find a book about Cauldron Hollow. This book can be found in a stack of books that is resting on a table at the Academy in North Freeport at 10.92, -7, -128.22 Copy , or in the Three Towers in South Qeynos, take the yellow portal, it is opposite from Sage Indis Surion 707.70, 82.36, 127.08 Copy . Right click it and inspect it to get a list of books in this stack. Read the Vanishing of Cauldron Hollow book. You can also read the other book to open up another quest.

After reading the book you should return to Arqis in Nektulos Forest.

Arqis will refer you to Dalninia, the Fairy in Nektulos Forest. Dalninia can be found at -196, 0, -342 Copy .

Dalninia will ask you to visit Queen Thayilia. Queen Thayilia is another fairy in the Nektulos Forest. She can be found at -499, 2, -292 Copy . She will ask you to slay Queen Dyleena.

Queen Dyleena can be found near the bone lake at -742, 145, -2199 Copy , way up past the top of N'Marr's Ascent. Take the Bird to Bone Lake Station.

After killing Queen Dyleena, go back and talk to Queen Thayilia, then Dalninia. Dalninia tells you you have to go and enter the Funeral Pyre -960, 12, -715 Copy and kill its 3 guardians. If you are doing this in a group then each group member must enter the Funeral Pyre to receive an update before killing the guardians or you will not all receive credit. The 3 guardians will spawn if you walk near the Pyre. Kill them, walk into the Pyre, and you'll be sent to go back and talk to Arqis.

Arqis tells you you must now light the Torches of Forewarning. To do this, you must visit the named treant Rulinthus who is quite near the Fire Guard (the wall that blocks lavastorm off at -47, 92, -2028 Copy , near the north end of Nektulos. Start heading towards the Fire Guard, but veer west into the dragoon-infested forest where the path curves from northwest to north and head west. Rulinthus is right next to the druid ring, slightly southwest of it. Talk to him and he sends you to kill Tilberbous (south of the Funeral Pyre at the southern end of the eastern river at -1051, -1.5, -581 Copy .

Tillberbous is found in the East of Nektulos, fairly near the road. Follow the road through wisp territory, take the right fork, and you'll get to an area with a lot of skeletons. If you look South while heading along the road, you'll see him. After killing Tillerbous, you must go back to Rulinthus.

Rulinthus gives you the twig which can be used to light the torches of forewarning, and the Gates of Cauldron Hollow quest finishes. Examining and snapping the twig that Rulinthus gave you will trigger another Access Quest "Cauldron Hollow: Lighting the Torches of Forewarning".
