Fixten

In a world where summoners wield the power to call forth vampires, elves, angels, demons, and all humanoid creatures from across the realms, Nathan found himself unable to summon beings except from beasts. 

However, those beasts are not ordinary beasts. They are divine beings who once stood at the same level, if not higher, than the legendary creatures the world ever knew. 

Casting his gaze to the left, Nathan sees numerous summoners accompanied by the likes of demon kings, archangels, vampire progenitors, and other legendary beings. Turning to the right, a massive army of alien symbiotes is waiting to attack. 

There was no fear in his eyes, because standing on his left is a majestic wolf who managed to kill a god, the legendary eight-headed serpent coils on his right, above him is the bird who is glowing like the sun, and behind him is a dragon that once gnawed the roots of the world tree. 

“Let the war begin.”

Summoners War: Only I Summoned Divine Beasts

Nathan thought of something, but he needed to hear more details before making a decision.

"If that's the case, can you tell me about noteworthy individuals the bases had?"

"Hmm…" Bella raised one finger. "For most bases, you only need to worry about a single grandmaster level summoner… more or less. In the main information network, they're normally guarded by several of them, so we have to be careful. Fortunately, there is no arcane level summoner we need to worry about, so it's manageable.

"However, in their headquarters in Rigan City, there is at least one arcane level summoner, which is their current boss. There should be a few grandmaster level summoners as well, so you have to be careful when fighting them."

"How about the cities they reside in?"
