Sigillum Maximum

The Seal of the Seven Secrets

"A princess. Seven seals. One choice that will save — or shatter — the Great Universal Realm."

Scroll

Seven kingdoms. Seven secrets. A black knight who will stop at nothing. And a princess who must find the light before the darkness consumes everything.

The Story

An epic journey across the Great Universal Realm

Aileen in her treehouse

When the Darkness Came

Princess Aileen is thirteen when a mysterious Black Knight invades her peaceful kingdom of Nuvolandia. Her mother is turned to stone. Her father is taken captive. The ancient Sigillum Maximum — the golden scroll upon which the security of all seven realms depends — has been stolen.

Sent through a hidden passage to the Elf Kingdom, Aileen must find the legendary Aeltiàfisar, the Knight of the Golden Light. Together with the fierce orc Grogher and the mysterious Dorcha — a boy with darkness in his blood — she embarks on a perilous quest across the seven kingdoms of the Great Universal Realm.

"Seven trials. Seven secrets. Seven keys to saving a world."

From the cloud-cities of Nuvolandia to the underwater palaces of the Merpeople, from the gnome kingdoms to the halls of the Elves — each realm holds a secret that could break the curse. But time is running out. And the Black Knight is always watching.

The Seven Realms

A universe built from light, shadow, and ancient magic

☁️

Nuvolandia

The Cloud Kingdom. A land of soft clouds, moonstone castles, and beings in constant telepathic contact with the skies. Home of Princess Aileen.

🌿

Elf Kingdom

An ancient realm of towering forests and luminous cities. Home to Aeltiàfisar, the Knight of the Golden Light, and King Baelkers.

⛰️

Gnome Kingdom

The Kingdom of the Two Rainbows. A subterranean realm of brilliant crystals, Pallafiocco tournaments, and ancient curses that still echo through the halls.

🌊

Merfolk Kingdom

An underwater realm of coral palaces and mother-of-pearl gowns. The merpeople hold secrets of the deep that even the oldest elves do not know.

🏔️

Dwarf Kingdom

Forged in the heart of mountains. Masters of craft, stone, and ancient metallurgy. Their secret is one of the seven that Aileen must recover.

Storm Kingdom

A realm of perpetual tempests. Home to the orcs. A people of immense strength, deep loyalty, and a secret buried in thunder.

Realm of the Great Light

The legendary domain where the Immortal Sovereigns retire. The source of the Sigillum Maximum's power. Few have seen it. None speak of it.
