Krag asked Havi Stagthorn to help by collecting the broken sword from Eliander's house, and taking it to the 17 The Dwarven Anvil, as the sword's inscriptions can't be translated until it's repaired.
Krag also mentioned to retrieve the key to Eliander Fireborn's house.
Eliander Fireborn gave Havi his house key.
Havi Stagthorn has given the key to Thornleaf Party whilst he looks after the Saltmarsh House.
