It says clearly. The bearer has the Destroyer Cult keyword and during the Declare Battle Formations step, the bearer can be attached to a Destroyer Cult unit (excluding Character units). If you do, the bearer’s unit cannot contain any models without the Destroyer Cult keyword. Add 3" to the Move characteristic of the bearer.

“If you do, the bearer’s unit cannot contain any models without the Destroyer Cult keyword” The wraiths don’t have it so they can’t be apart of the unit so it’s not legal. Right?
