In that case the other shapeless mass had to be Rogen. He had been wondering what would happen if he was hit directly by the Mana Storm and now he had his answer.
Death was not the worst possible outcome.
Because of the myriad of spells coexisting within the Mana Storm the effects on their victims were unpredictable. If they were hit, it was the end, but that end could take many forms.
In their current state, Gerulf and Rogen could no longer even be considered living beings. Even their Spirit Bodies and souls had gone through a change of form and nature and Gerulf uttering his name was just his last instincts trying to formulate a coherent thought before fading into oblivion.
Because his mental sense melted away as soon as it came in contact with the Mana Storm, Jake couldn't say for sure what was happening to them, but from what little he could see with his Myrtharian Eyes, the two giants had delayed their deaths by using a method similar to Vhoskaud and himself.
