Many Titan artifacts remained on Azeroth, and they shared one very distinctive trait: an exceptional capacity to store and channel energy.
Both the Forge of Origination hidden in the Halls of Origination far away in Uldum and the Nalak'sha Engine on the continent of Pandaria proved this. Even though the Titans had left this world hundreds of thousands of years ago, the devices they had left behind still operated almost perfectly. No one could explain why the Titanic energy powering them had never dissipated.
Perhaps the Star Spirits possessed energy manipulation techniques far beyond anything Azeroth's mortals could imagine, or perhaps there was something unusual about the energy itself. Whatever the case, Titanic energy was not merely stable. Under certain circumstances, when used to attack, its power was absolutely not to be underestimated.
C'Thun's death had proved this. Facing the weakened Old God that had just escaped its prison, Dick had released the energy within the Titan prison beneath the Temple of Ahn'Qiraj. Unleashed through abnormal means, that Titanic energy had been unimaginably violent, tearing the Many-Eyed Fiend's body into tens of millions of pieces. And now Yogg-Saron, whose body had swollen to more than five times its size in an instant, would become the next victim of this property.
With every passing second, the Titanic energy pouring into the Old God's body through Val'anyr, Ancient Keeper's Warhammer, which Yogg-Saron had swallowed, made his body swell further, like a balloon being rapidly inflated. And the reason Dick had put the warhammer Val'anyr inside a Runecloth bag instead of using it directly in combat was... the Paladin had never intended to repair it completely.
A fully repaired warhammer would merely have been a powerful weapon, but a half-repaired Scepter of the World, barely able to maintain its shape, was the perfect
