The Gods struggled against the Primal. They had a numerical advantage, and the Primal were restrained by the lack of Essence in the Beginning, yet the Gods didn't gain on the ground against the Primal.
Fenrir transformed into a flash and pounced the nearest Primal, his massive claws coated in the power of Extraction. However, before his claws could hit the target, the Primal either disappeared, evading the attack, or an Essence Wall erupted before him. The Essence Wall wouldn't last long against Fenrir and his Extraction-coated claws, but they were strong enough to stall him for a few seconds.
That gave the Primal enough time to counterattack or to deal with the other Gods. The Primal chose to do both. He created hundreds of Essence Spears on a whim and attacked Fenrir with half of them, forcing the great wolf to retreat.
