Obelisk of Order

Obelisks of Order are massive crystalline formations dotted across the Shivering Isles. These are usually inactive, but when they are active, the largest central crystal will rise and hover above the rest on a column of shock energy. Active Obelisks will have a Priest of Order who guards it, along with the Knights of Order that spawn from the Obelisk. Kill the Knights and use their Heart of Order on the Obelisk until it deactivates. Remember that the Priest will revive him or herself a few times before you will finish. The Priest, if still alive, can completely reactivate inert Obelisks of Order.
