At the Maelstrom, as Patrick began using the Teleportation Spell, the phantom image gradually began to take physical form.
Draenor's former sea level aligned with Azeroth's. With Thrall balancing the elements and then having them locate Outland's former sea level, it was a simple task.
From top to bottom, Outland's phantom image slowly became whole, working inward from the outside. As each stretch of land materialized, the seawater was slowly pushed aside. Outland's crust and mantle extended into the deep sea. After reaching the seabed, Outland's mantle would merge with Azeroth's, while Outland's excess mantle and crust were severed.
Thrall led the Earthen Ring in connecting with the earth, checking whether it was stable. Therazane the Stonemother led the earth elementals in adjusting the height of Azeroth's land through the previously repaired World Pillar, eliminating some of the adverse effects brought about by the slight rise in sea level.
Of course, Shadowmoon Valley's environment was harsh. It was a region thoroughly polluted by fel. The contamination of the land was manageable; after all, Quel'Thalas had already set a precedent by cleansing the Dead Scar. It would merely take more time, and Shadowmoon Valley's environment could eventually be changed. However, Patrick needed to discard the fel-contaminated lava and rivers in places such as Gul'dan's Hand, the Fel Pool, the Shadow Altar, Krazzworks, and Sketh'lon Base Camp.
Fel was far too corrosive to life. It could not be allowed to contaminate the Great Sea.
As the Teleportation Spell was fully activated, the Titans Runes in Outland's sky gradually appeared in Azeroth's sky.
The ley line was like a "cell membrane" around Azeroth, and cell membranes were fluid. The runes within Outland's ley line began connecting with those within Azeroth's.
Once Outland's replicated Titans Runes had finished aligning with Azeroth's originals, Patrick channeled
