Mind flayer (windmill)

The windmill Mind flayer is a notable mind flayer that is sleeping underneath the Abandoned Windmill in Rivington during Act Three. It is starved, as a result of its recent ceremorphosis.

Involvement

Act Three

If a party member interacts with the mind flayer,  The Emperor informs them that it is a recently transformed mind flayer, and ushers them to kill it to consume its power. The party can sneak away via a Stealth check or awaken the mind flayer.

Upon waking up, the mind flayer notices the party's tadpoles and asks for a fresh brain to consume, which initiates ⁠Feed the Mind Flayer. The party can bring it a fresh corpse, tell it to find its own food, or kill it. The first and third options grant a free Illithid power.

If the mind flayer is fed and not killed, it ventures to the Lower City and murders the Armbrust family. After this it remains in their home until it is discovered by the guards.

According to  Absolute Orders: Newborn, which is carried by the mind flayer, its former name could have been Alyan, a member of the Flaming Fist.

The following inspiration can be earned based on the choice to feed it or kill it:

• ⁠Kill 'Em While They're Young ( Haunted One backgrounds) - for killing the mind flayer
• ⁠Newfound Subject ( Noble backgrounds) - for feeding it
• ⁠Unexpected Parenting ( Haunted One backgrounds) - for feeding it

Providing the mind flayer with a dead body to feed on is considered an oathbreaking action for  Vengeance Paladins,  Ancients' Paladins,  Paladins of Devotion, and  Paladins of the Crown ^[verify].
