The Temple at Senntisten

Go to the Exam Centre.

If you asked Ali for help getting there, he gave you a Dig Site pendant (or Ali's pendant if you have not unlocked the ability to create Dig Site pendants) to teleport directly there.

Alternatively, teleporting to Varrock Dig Site with either pendant for the first time will grant you the Return to Senntisten achievement.

Talk to Dr. Nabanik outside of the Exam Centre south of the Digsite.

Talk to Terry Balando inside the exam centre for a restoration certificate.

Talk to Dr. Nabanik. He will give you a rope.

Use the rope on the winch in the north-east dig site, north of The Stormbreaker ship.

Operate the winch to enter the Digsite dungeon.

Talk to Azzanadra in the southern part of the dungeon.

Open the ruined backpack for a battered letter and heat globe.

Read the letter and then talk to Azzanadra.

For more information on how to kill the Barrows Brothers, see this page.

Travel to the Barrows.

Kill the six Barrows Brothers found in their tombs below the ground.

Barrows amulets can be used to skip killing up to three brothers.

Amulets can only be used on the tombs before the brother is summoned.

The final brother must be killed without using an amulet.

Once all six brothers are dead, search the chest at the centre of the tunnels beneath the crypts to get the Barrows icon.

Go to the Ghorrock fortress:

First use the canoe near Erjolf from Tale of the Muspah for a quick access. It is located on the west coast of the Rellekka Hunter area, north of fairy ring code.

Go east and place the heat globe on the pedestal near the ice block entrance.

Squeeze past the ice block.

Enter the fortress through the south entrance and climb-up the stairs to the west.

Run to the south-east corner of the castle and climb-down the stairs east.

Scale up the damaged wall north of the door.

Climb down the smashed rampart in the north-west corner.

Enter the trapdoor in front of you.

Run east and take the heat globe.

Return to the entrance room of the basement, and place the heat globe on the pedestal on the west side.

A waterfiend will be released. It is immune to fire damage, but does not need to be killed.

Go inside the west room, then right-click the radiant pedestal to cast Telekinetic Grab on it.

Use the globe on this room's pedestal. Go down the trapdoor.

A waterfiend will be released. It is immune to fire damage, but does not need to be killed.

Pick up the globe in the southern room.

Use it on the pedestal back in the northern room with the ladder. 2 waterfiends will spawn.

Loot the crates in the south room for 40 law runes and 300 air runes.

Go to the east room and take the globe from the pedestal for an imperfect heat globe.

Exit the dungeon the way you entered.

Scale the damaged wall to the west, then head to the north-east corner to the destroyed pedestal.

Insert-globe in the smashed globe-holder on the ground.

Choose the push option on the smashed globe-holder on the ground.

After a cutscene, climb down the smashed rampart in the north-west corner.

Return to the dungeon by re-entering the trapdoor.

Go down the trapdoor in the western room.

Run through the dungeon and take the heat globe from the pedestal in the southwestern corner.

Head back east through the hallway you ran through until you reach the southeast corner, where the path turns north.

At that corner, look for a pipe on the south wall.

Choose the "Place-globe" option on the pipe.

Choose the "Whack" option on the pipe.

Continue into the southeastern room and climb the ladder to go up.

Be sure you are not in group, otherwise no loot will drop from the monster.

Head west and kill the ice demon (it cannot be damaged by water spells).

Take the Frostenhorn that it drops.

Return to Azzanadra with the items back at the Senntisten Temple underneath the Dig Site.

The Dig Site pendant can be used to teleport outside the temple (option 2).

Back outside near the winch, talk to the Assassin for a relic.

Return to Azzanadra.

After the cutscene, speak to Azzanadra again.
