Effire still thinks forcing young Morphyx into decades-long shapeshifted bonds with strangers is bullshit, "sacred duty" or not. And he'd wager that if there was any human (i.e. Tu Naul) decision-making involved in pairing him with Morgen it was something along the lines of "let's put the two weirdos together so nobody else has to deal with them."
But he is glad he decided to stay.
