Making History

Talk to Erin the silver merchant at the north-western stall in East Ardougne market and borrow his enchanted key. It changes temperature as you walk.

• Spade

He will not talk to you if you have recently stolen from his stall.

Go to Castle Wars, cross both northern bridges, and stand about four steps north of the east side of the second bridge. When the key steams, dig.

Open the chest with the key.

Reach Port Phasmatys by charter ship, or pay two ecto-tokens at the gate if Ghosts Ahoy is unfinished.

Earn ecto-tokens at the Ectofuntus north of the port: grind bones upstairs, take slime from the trapdoor west of the fountain, use both on the fountain, then claim from a ghost disciple.

Talk to Droalak in or around the general store. He gives you a scroll in exchange for a sapphire amulet for Melina.

Talk to Blanin near the dairy churn east of the Longhall first — he tells you what you need to answer his brother's questions.

Dron is near the northernmost dock, north of Skulgrimen's Battle Gear. He quizzes you on what Blanin said.

The dialogue options in order are 3, 2, 2, 1, 2, 1, 2, 2, 1, 3, 3, 1, 1, 1.

Take all three accounts to Jorral. He gives you a letter for King Lathas, upstairs in the Ardougne castle across the river.

Lathas returns a letter promising not to demolish the outpost. Take it back to Jorral, who turns the outpost into a museum.
