By this stage of the War of Light and Dark, the regular battlefields were basically the Wrynn Family's domain.
In the Primal Abyss, Arthas, who had betrayed the Wrynn Family, had already become a Grand Marshal commanding the armies.
On the side of the Light Alliance, the Wrynn Family's legions were the absolute main force.
The Myconid Race had followed Luna to help. The Mycelium Construct Legion and Spore Goblin Legion under her command were still at the forefront of the battlefield.
Influenced by Arthas, the Bone Spirit Legion could only be deployed under Anduin's command.
But that wasn't Medivh's only force. The War Goblin Legion was active on the battlefield.
The racial legions led by Medivh's children were also a mainstay.
For example, Galio's Justice Colossus Legion and Garen's Crownguard Legion.
While Anduin fought on the front lines, Medivh's eldest daughter, Jaina, stayed home to guard it alongside the Elemental Tower Spirits.
Wherever the Legion of Light went, Block City was built in its wake.
Jaina repeatedly repelled the Abyssal armies' counterattacks, continually squeezing the Abyssal Demons' room to maneuver.
Arthas was good at running, huh? Once she filled the Primal Abyss with Block City, she'd see where he could hide.
"Jaina, this world needs light!"
The lords of the Elemental Realm had been watching the War of Light and Dark from the sidelines all along.
Having once received the Goddess of Light Athena's blessing, the Elemental Lords hoped all the more that the Star Sea would be ruled by light.
So when the Elemental Tower Spirits blew up Block City after Block City to unleash Chaotic Elemental Storms against the Abyssal Demons, the Elemental Lords pretended not to see.
As the War of Light and Dark continued, it became harder and harder to tell which side would emerge
