Requiem for a Dragon

Head east to the rowboat docked next to the Grove cabin.

Interact with the rowboat to travel to Ungael.

You will spawn next to hostile Zamorakian scouts; praying against Ranged can be helpful. This is a safe encounter, and you will respawn outside of the rowboat upon death.

Run north-west past the scouts and enter the colossal cave.

Head north-west and approach Vorkath.

Inspect the crystal shard in the backpack.

Return to the Ungael beach, this time travel up the north-east path, up the hill and interact with the Ruins Entrance to enter.

Head north, just in front of the Imposing Statue, and interact with the doorway to the south.

Follow the path south-west and kill the translator.

Pick up the dropped Zamorakian translator's notes and read them.

Search the bookcase on the northern wall for Zorgoth's Journal.

Search the shelves immediately southeast for a broken focus.

Inspect the dragonkin mural on the western wall.

Pick up the congealed potion in the south-eastern corner.

Listen to the Archivist about all findings.

Return to Fort Forinthry and enter the floor hatch east of the Command Centre (south-east).

Talk to Zemouregal.

If your Necromancy level is 120, you can skip most of the conversation

Otherwise, you must follow further dialogue options

Head to the City of Um and talk to Death.

Talk to the Tree of Balance, south of the Archaeology Guild.

Head to Memorial to Guthix (do not enter the Hall of Memories)

You can teleport directly there using memory strand or Sixth-Age circuit, otherwise teleport to Eagles' Peak lodestone and run north-west

South-east outside the memorial, uncover both fertile soil spots

Excavate both halves of the soul beacon from the uncovered standing stone debris and runic debris. There is a material storage container just north of the spots.

Damaged soul beacon (base)

Damaged soul beacon (core)

Return to the Tree of Balance with the two damaged parts.

Head to any archaeologist's workbench to restore the damaged soul beacon.

Return to the Tree of Balance with the restored soul beacon. Chat options can vary, but the correct order is: Change, Elemental, Commune, Change.

Return to the City of Um and talk to Death.

Complete a soulfarer ritual at the Um ritual site.

Travel to Fort Forinthry and take the boat back to Ungael.

Return to the colossal cave in Ungael and head north.

Repair the 13 spots of the ruined ritual site, just east of Vorkath.

Set up the soulfarer ritual.

Perform the ritual. A cutscene will begin.

Note that this is a safe encounter, and you will respawn outside of the rowboat upon death.

Perform the ritual again, pausing to:

Kill Vengeance whenever she appears. Vengeance can drastically drain your stats so super restores can be useful. Deathtouched darts can be used. If you use speed III on spare ritual space, and speed II or higher in necromancy cape, and never miss a shadow rift, you will only have to kill Vengeance once.

Close any Shadow Rifts as soon as they appear. Continuing the ritual while a Shadow Rift is open will reverse the ritual's progress meter.

Watch the cutscene.

Head west and inspect Vorkath.

Talk to Death in City of Um.

Head south-east, south of Selene and directly north of the large cave opening in the southern part of the city and approach Vorkath.

Return to Fort Forinthry and enter the floor hatch east of the Command Centre.

Talk to Zemouregal to complete the quest.
