Now that's a surprise, you're back in your home village of West Harbor. Go through the village and head for the swaps. You might remember that next to the ruins where you got the shard there was a second ancient construction - this time you're headed there.
Enter the ruins to meet your first Shadow Reaver. You'll witness the destruction of the last statue. Defeat all the enemies and use the portal in here. It's time to go back to the Keep.
