Ebony Tower/Map

It was discovered on the fifth level of the Ebony Tower. Its runes and the images were cut into an indestructible stone that even divine fire couldn't destroy.^[1]

The areas on the map seemed disconnected. There were no borders, no terrain, and no measure of distance between them. The ideas of north, south, east, and west were assigned to the map for reference. It could have been the exact opposite, or impossible to apply to the logic of the map altogether. But it somewhat fits with the geography of the Dream Realm. Each of the images had an inscription near them, written in an unfamiliar runic language. It was similar to the one used by the Spell, but also different enough to make translation either impossible or difficult.^[1]

The Demon of Destiny had left a map of strongholds built by his siblings in various realms.^[2]

The runes and the strange map carved into the obsidian wall on the fifth level of the Ebony Tower shows six landmarks: the Ivory Tower, the Tomb of Ariel, Ravenheart, Bastion, the great vessel for the House of Night, the Underworld, and Weaver's Mask. The other six strongholds are marked by a single rune each. The map could be a realm map, as the daemons built their citadels in different realms. The carving of Weaver's Mask signifies that Nether did not know where his eldest siblings lived or if there was such a place.^[3]

	The mountains depicted in the center of the map were the Hollow Mountains.[1]
	An image resembling the Ivory Tower, which represented the Chained Isles.[1] Inscription The inscription cut into the stone near the image of the Ivory Tower were runes that closely resembled those usually used by the Spell. It was "Desire". The other meaning of the runes was hope. The Ivory Tower had once belonged to the Demon of Hope.[1]
	The castle to the south is Bastion based on its silhouette and appearance that was staged for countless dramas, movies, and webtoons.[1]
	The great stone bridge nestled between a snowy peak and a raging volcano — was the road to Ravenheart, the great Citadel ruled by clan Song.[1] See also: Jade Palace
	The ship sailing on the ghostly waves represented the Stormsea, where the citadel of the third great clan, House of Night, was located.[1]
	There was no familiarity with what the pyramid to the east represented.[1]But during the chain of gates in Antarctica, it seemed like the gates are all connected to a new area in Dream Realm filled with blooming Nightmare Seeds and frenzied Nightmare Creatures. A giant black pyramid appeared as a haunting mirage.[4] It was implied in the rune description of Shroud of Graceless Dusk that the black pyramid had something to do with Ariel, the Demon of Dread.[5] See also: Tomb of Ariel
	The seventh image meant Weaver based on the inscription near the depiction of the mask that said "Fate?".[1] The depiction of Weaver's Mask was drawn on the wall of the Ebony Tower, representing Weaver, was placed north of the Hollow Mountains, above all six strongholds, suggesting no one knew where Weaver's stronghold was or if he had one. So, Nether had drawn it outside the map.[2]

There were seven images on the map that might be the representation of the domains of seven daemons.^[1]

Based on the runes and images on the map, there are three things that can be speculated:

• The three great clans had inherited their Citadels from three daemons or at least built their strongholds in the regions of the Dream Realm where daemons had once dwelt.^[1]

The Citadels of the great clans were left behind by the seven daemons and very important to the Sovereigns.^[6]

• Ivory Tower, which had once belonged to Hope.^[6]
• Hollow Mountains, where Nether's Citadel still remained undiscovered.^[6]
• Ravenheart was actually the Citadel left behind by Ariel.^[6]
• It was unknown what daemon would be more connected to the Tomb of Ariel than its builder, Ariel.^[6] In the Third Nightmare, it was revealed that the Tomb of Ariel is the burial site of Oblivion.^[7][8]
• The Great Citadel of House of Night was connected to the Demon of Repose.^[8]
• Bastion once belong to the Demon of Imagination.^[8]

• The Underworld, most likely, was situated beneath the Hollow Mountains. This Death Zone was the very dark and cavernous domain to which the Nether had retreated after his conflict with the Goddess of the Black Skies.^[9][1]
• The ruler of the beautiful and prosperous land that had invoked the wrath of the Sun God and doomed their kingdom to destruction and eventually transformed into the Chained Isles, was a daemon, as well.^[10][1]
