Obrin Ruins were a set of ruins located over a small lagoon on the northeastern side of the old Hall of Memories. The area was kept behind a locked gate and could not be accessed; however, the point of interest could still be discovered by approaching the gate.
- Prior to the April 2014 Feature Pack, this area was known as Waters of Obrin. It was devoid of ruins and contained a few training golems for testing underwater abilities, which were also removed from Structured PvP with the feature pack.
- During Wintersday 2015, the gates were removed and the ruins were reverted back to a lagoon with training golems and Underwater Combat Master NPC. However, the map objective names did not get reverted.
