Pillars of Creation

The Pillars of Creation are five mighty titanic relics used ages ago by the Titan Keepers to shape the world of Azeroth. When the Burning Legion created another secondary portal during the War of the Ancients to flank the kaldorei, the Highborne used the Pillars to seal the portal.

The Pillars somehow became scattered about the Broken Isles in each of the regions and forces of the Grand Alliance and Horde ventured to retrieve them during the Legion's third invasion of Azeroth after Archmage Khadgar stated that the five Pillars would be capable of sealing off the Tomb of Sargeras, where the demons came from, similar to how they were able to seal off one of the two Legion portals during the War of the Ancients ages ago.

The five Pillars are the Aegis of Aggramar, Tidestone of Golganneth, Eye of Aman'thul, Hammer of Khaz'goroth, and Tears of Elune - all named after members of the Pantheon of Titans, except for the Tears of Elune, which was named after the Moon Goddess of the same name.
