Unwanted Legacy

Near the beginning of Chapter 2, Harrim will inform you about ancient dwarven ruins.

After meeting Ekundayo, the location of the ruins will be revealed.

Ensure Harrim is in your party before traveling to the ruins. If you have already cleared the Dwarven Ruins, Troll Lair, and Troll Lair Depths, you can return to your capital, add Harrim, and walk him through these areas to complete the quest.

From the Ruined Watchtower, travel Southeast, South, South, South, South, then West to reach the ruins.

Upon entering the Dwarven Ruins (also known as the Troll Lair), you will encounter Kobold warriors. Defeat them.

Proceed West, then North to fight two Trollhounds and a Troll.

Continue East to the entrance of the Dwarven Ruins/Troll Lair. In the courtyard, you will face Branded Trolls and Greater Trollhounds.

If Harrim is with you, examine the dwarven statue east of the Troll Lair entrance.

Rest your party fully before entering the main area of the Dwarven Ruins/Troll Lair.

Inside, examine the statue of Torag that Hargulka demolished. Pass a [Lore (Religion) 15] check to unlock a specific dialogue option and obtain an item needed later.

In the Troll Lair Depths, defeat Jazon, other Trolls, and Kobolds.

Examine the glowing rune on the northeastern wall. Save your game, then interact with it and pass a [Lore (World) 17] check to unlock a specific dialogue option.

Proceed to the throne room of the Troll King in the northwest of the Troll Lair Depths.

After defeating Hargulka and Tartuk, interact with the anvil in the center of the room.

Save your game, then interact with the anvil and pass a hidden [Lore (Religion) 17] check. If you have examined all four relics and passed all three hidden skill checks, you will obtain the Heart of the Anvil. Otherwise, Harrim will punch the anvil once instead of twice.

Exit the ruins through the southwest of the throne room.
