As illustrated in the Shadowhunter's Codex.
A Raum is a demon whose most dangerous weapon is its tentacles—slick, gray-white, and tipped with red suckers, each of which contains a cluster of tiny, poisonous needle-like teeth. Their poison is slightly more complex than a Drevak sting but is still manageable.[1]
Description[]
Intimidating and dangerous, Raum demons are clever opponents despite being incapable of speech and generally unintelligent. Raums are the size of an elongated human and possess white, scaled skin, bulging black, toad-like, pupil-less eyes, a perfectly circular mouth. Raums make distressed, hooting noises, move incredibly fast and are known to be retriever demons.[2]
Brood mothers[]
Raum brood mothers are generally larger than Raums. They are described as looking like a tree made of smoke and an octopus with its roiling skin and several long black tentacles. They have no bones and can regenerate its flesh, organs, and limbs quickly. Thus, you cannot kill them easily by chopping off body parts. The only way to kill one is to tear it apart from the inside.
Brood mothers are hard to employ as it takes powerful magic to coax one out of its lair. They are also able to conduct magic of their own to form pentagrams and Portals. When doing so, the tips of their tentacles glow.[3]
History[]
Valentine Morgenstern once summoned Raum demons and sent two of them to Luke's home to retrieve the werewolf Maia Roberts. They attacked Luke on his lawn and knocked him out, bringing him to the waterfront across the street from his house. Jace's Sensor detected their presence, and Clary noticed their movement by the bank of the East River. Jace tortured one, threatening to strike its heart, which Valentine taught him when he was young, to tell him Valentine's location, and the other escaped into the river just as Clary drew her seraph blade to fight it. Luke then realized that the demon might still be looking for Maia.
There were also Raums among the myriad of demons summoned and kept aboard Valentine's ship.
Weeks later, while walking up to Luke's house, Clary reminisced with Simon their first encounter with the demons.[1]
When Alec Lightwood and Magnus Bane were aboard the Orient Express, they were attacked by many Raum demons which had been summoned by the warlock Shinyun Jung to capture Magnus. Among them was also a Raum brood mother, which Alec had never seen before. The Raum demons were dispatched by Alec and Magnus, while the brood mother was killed by Shinyun herself, to make Alec and Magnus trust her.[3]
