Egret Harpy Friends. Scarlet ibises congregate with egret harpies (see page 195) and enjoy mutual protection. Uninformed observers believe the ibises are the harpies' pets, at least until they witness conversations between the two. Egret harpies never ask the ibises to curse enemies regardless of circumstances, but ibises who witness or know of attacks on egret harpy companions take it upon themselves to inflict bad luck in revenge.
