Murrenreue

Murrenreue (ムレンロイエ, Murenroie) is an archduke candidate from Immerdink and currently studies at the Royal Academy.

Despite often complaining about how Ehrenfest was at fault for Immerdink's fall in the rankings and lamenting how nobody talks about how hard they have it, Murrenreue quite brazenly asks Lady Rozemyne to join the joint research project Ehrenfest has with Dunkelfelger, during a tea party Ehenfest has with lower ranking duchies. To everyone's surprise, Rozemyne is actually supportive of this idea, though naturally since it is a joint project, Dunkelfelger needs to give their permission as well.

As a result, many duchies are allowed to participate in a Dedication Ritual held at the Royal Academy, but Dunkelfelger makes it a hard requirement that any participating duchy needs to first play them in treasure-stealing ditter. Due to losing so many of their apprentice knights to the ternisbefallen unleashed by the rebels in last year's attack on the royal family, during the award ceremony, they feel unable to meet this requirement and forego participation in the Dedication Ritual, despite being the ones to spark the participation of other duchies in it.

The next year, Murrenreue seizes on the rumours that Rozemyne is going to be demoted to archnoble status and sent to the Sovereign Temple to become the Sovereign High Bishop, to insult and humiliate her, at the fellowship gathering. Rozemyne and her siblings decisively deny this and proclaims that Aub Ehrenfest would only allow such a thing to happen, if all other duchies had to also send an archduke candidate to the Sovereign Temple. She further counters that, should this come to pass after all, she would be looking forward to working with her in the temple, causing Murrenreue to be the one humiliated instead. After this put-down, no other lesser duchy dares to broach the subject with the Ehrenfest archduke candidates.
