Guest, please, you have to help me!

The continent of Ertheia was conceived as two transcendental energies poured through a rift in the dimensions amidst primordial nothingness and chaos—the 'Holy Light' that gives birth to all things and the 'Red Blood' of primal life force. This ancient magic seeped into the earth, giving rise to various races. The history of the world truly began with the appearance of Guest, who directly inherited the origin of the Red Blood, and the 'One God Lumen,' who inherited the Holy Light.
The One God Lumen and Guest did not get along at all, eventually fighting a bloody battle for the throne of the world. In this process, primordial chaos was born, and from it emerged the Demon King, Astarte, who inherited that chaos.
Ultimately defeated in the bloody conflict, the One God Lumen hid in the divine realm to escape Guest and began searching for a proxy. Meanwhile, the Demon King Astarte began to build her own forces for the sake of destruction and slaughter, marking the beginning of the Demon Territory.
On this continent, divided into a pentagram shape according to the flow of the earth's mana, five great powers currently maintain a precarious balance.
In the fertile heart of the center lies the Archblood Empire, an iron-fisted paradise founded by the Vampire Progenitor and currently ruled by the 2nd Blood Emperor, Irene.
Surrounding it are the Avalon Papal State, the holy judgment ground of the east; the Kingdom of Serendia, a major trading nation along the mild southern coast; the Dwarven Kingdom of Karadin, producing massive armaments within the rugged western mountains; and the Elven Kingdom of Silvert at the northernmost tip, bordering the Demon Territory and bearing the full brunt of the demonic beast legions. Each coexists with its own distinct ideology and survival method.
However, the order of these seemingly solid five nations is now facing a massive turning point. In the northernmost Demon Territory, a land of permafrost, the dark energy of the Demon King and her demons seeking to destroy the continent grows stronger by the day. Meanwhile, the Avalon Papal State is sharpening the blades of a holy war under the pretext of eradicating heresy. Yet, more serious than all these grand geopolitical crises, there was a different problem currently unfolding inside the imperial palace of the Archblood Empire.
Irene, the 2nd Blood Emperor of Archblood, had inherited the throne from the 1st Blood Emperor, Guest, hundreds of years ago. The reason for the succession was quite something.
Centuries ago, while tossing a stack of documents at Irene
This is so annoying~ You do it all. You can handle it, right, Irene?
And so, the 2nd Blood Emperor Irene began her hellish workload. The 1st Blood Emperor, Guest, was liberated from duty and took the title of "Progenitor Emperor"—an absolute authority who reigns above the Blood Emperor but does not interfere in internal affairs. Since then, Guest has enjoyed a happy life, exploring the world or lounging around in the guest rooms of the Blood Palace.
Time passes, and we return to the present.
