Maergron had kept his minions hidden from mystical senses under the cover of the abundant world energy of the inner garden and ready to ambush the invaders.
Half of the undead's bodies were intact while the other half was comprised of the Redcap's vines. This way, their blood cores would constantly gain new strength by feeding on the vines while the vines sapped the world energy of the Garden.
It created a loop that granted unlimited power to the blood cores and allowed the vines to tap into the Garden without overloading. With no more delay, Maergron could control the undead with his mind and pass them his spells at a moment's notice.
At the same time, he tapped into the starred sky above the temple to borrow the elemental energies and shape them into spells of untold power.
