· The Elbaf mural depicts a giant serpent said to have destroyed the world, raising the possibility of this serpent appearing as the final boss of the Elbaf arc.
· Loki's recent transformation into Nidhogg matches the dragon in the Elbaf mural in appearance, including its horns and teeth.
· This implies that Nidhogg users existed in the past, and they were beings who fought against giant serpents to protect the world.
· Loki's massive Nidhogg transformation is on a scale that Killingham's Muma cannot contend with, significantly impacting the current development of the Elbaf arc.

· Killingham, who ate the Solvent Length, possesses the 'ability to manifest dreams.'
· The core secret of this ability is that the power of manifestation changes depending on the 'amount of information' the dreamer possesses.
· There's an instance where Killingham made Soji recall salt, and a specific salt, 'Aspech Rock Salt,' was manifested based on Soji's experience.
· The monsters dreamed by the children of Elbaf, lacking war experience, were manifested as fairytale-like figures and had weak combat power.
· Conversely, the 'Mama Muma' dreamed by mothers born in the warrior era were manifested powerfully, unlike other Muma, because they were the closest and most familiar beings to their children, completely defeating the Giant Pirate Crew.
· As Scopper Gaban mentioned, this ability manifests more accurately and powerfully in proportion to the dreamer's amount of information.

· Killingham's ability grows stronger the more allies capable of having terrible nightmares are around.
· Currently, the being most capable of having powerful nightmares around Killingham is 'Imu.'
· Imu has lived for over 800 years, already knew the previous Nidhogg users, and their experience likely contains information about countless monsters and Nidhogg's natural enemies.
· To confront Loki (Nidhogg), Imu is highly likely to intentionally have a nightmare featuring Nidhogg's natural enemy and use Killingham's ability to summon this monster to Elbaf.
· The identity of this monster is theorized to be 'Jörmungandr, the Serpent of Ragnarok.'
· The Elbaf mural from the 1st century depicts Nidhogg (Thor motif) fighting a giant serpent, and in Norse mythology, Thor's arch-nemesis is Jörmungandr.
· Jörmungandr is a colossal deep-sea serpent said to have destroyed the world, and during Ragnarok, it was Thor's fated rival, with both killing each other.
· Imu would be well aware of this millennia-long rivalry between Nidhogg and Jörmungandr and will summon the true form of Jörmungandr, which only they can recall, using Killingham's ability.
· Ultimately, the final boss of the Elbaf arc is expected to be Jörmungandr, the deep-sea serpent who has confronted Nidhogg since ancient times, rather than Imu.

· The author previously hinted at Jörmungandr's appearance in the Fish-Man Island arc. When the Straw Hat Pirates arrived in the deep sea, a giant sea serpent with red eyes appeared, metaphorically representing Jörmungandr, hidden in the deep sea, awaiting Ragnarok.
· Furthermore, by drawing a giant tree nearby (hinting at the World Tree Yggdrasil), it foreshadowed Jörmungandr's appearance in a future arc (Elbaf) where a giant tree would be featured.
· In the cover of Chapter 600, Chopper dreams of being a magnificent reindeer and strikes a pose, but the raccoons draw Chopper as a raccoon just like themselves.
· This is interpreted as a hint that while Imu imagines an incredibly terrifying Jörmungandr, due to Killingham's lack of proficiency, a somewhat crude-looking Jörmungandr will be summoned.
· Chopper imagining a reindeer aligns with Soji imagining salt, demonstrating the difference between the dreamer's amount of information and the manifested result.

· Imu appears to be using Killingham's ability to summon Jörmungandr, Nidhogg's natural enemy.
· The Jörmungandr conjured from Imu's vast experience and knowledge will likely be powerful, but it might not be perfectly manifested depending on Killingham's proficiency.
· The appearance of Jörmungandr, unleashed from Imu's dream, will be a crucial turning point in the Elbaf arc.
