- "That's why everyone gives in to a Bor. Not to make the pain stop. But so there's something left of you afterwards."
- ―An Imperial interrogation officer
Mairan, also referred to as mind flayers, or as Bors, were a sentient multi-tentacled multipod species that were native to Maires. They had the unique ability to read minds, and as a result, they were often used as a form of torture by the Galactic Empire and the Partisans.
Biology and appearance
- "Bor Gullet can feel your thoughts. No lie is safe. [...] Bor Gullet will know the truth. The unfortunate side-effect is that one tends to lose one's mind."
- ―Saw Gerrera, to Bodhi Rook

Mairan, sometimes known as Bors,[5] were a sentient[1] multi-tentacled multipod species hailing from Maires.[5] They were unique for being able to read minds and erase, or alter, memories.[2] It was known for some individuals, such as the Imperial shuttle pilot Bodhi Rook, to lose their minds after having their mind plundered by a Mairan.[3] The Imperial Security Bureau conducted "Kadiopa experiment 9484-2"[6] sometime before or during 3 ABY [7] where they used a bor to exude false intel provided by a plant from a group of prisoners. The ISB noted that several of the prisoners were left with permanent neurological damage.[6]
Mairans in the galaxy
- "Why, for this very prisoner we are defrosting a bor of the Mairan—one of only three in Imperial hands."
- ―An Imperial warden, to Magna Tolvan
Saw Gerrera's Partisans kept a Mairan named Bor Gullet.[3] During the Galactic Civil War, the Galactic Empire kept three Mairans in ice, occasionally defrosting them to interrogate prisoners,[8] with Bor Ifriem being used to interrogate Chelli Aphra in Accresker Jail.[2] Decades later, Harra the Hutt kept a Mairan at her stronghold on Vodran. At one point it was used on Cost Niktur.[4]
Behind the scenes
Mairan first appeared in the Gareth Edwards' 2016 anthology film Rogue One: A Star Wars Story.[3] Although the canon novel Join the Resistance: Escape from Vodran, written by Ben Acker and Ben Blacker, identified them as Bors,[4] Doctor Aphra (2016) 21, a canon comic written by Simon Spurrier and penciled by Kev Walker, identified the Mairans for the first time.[8] In Star Wars legends, the Mairan first appeared in the novel Young Jedi Knights: Lightsabers, written by Kevin J. Anderson and Rebecca Moesta.[9]
