Siege of Darguun - Part I - The long march to war
Dragonshards received from Oalian
Following the completion of a quest, the leader of the Eldeen Reaches, Oalian gave the heroes three large dragonshards: a Khyber shard, a Eberron shard and a Siberys shard. The shards are sources of great power, which could be used to power siege engines.
Currently, the dragonshards are being held in a House Kundarak bank in Passage.
