He is seen wearing a long black coat over a white shirt and stripped pants, and ties his blond hair into a queue with a red ribbon. A sword is strapped to a simple belt around his waist. The edges of his coat and boot-tops are embroidered with golden crosses, and he wears a metal chain-and-cross around his neck.
He was first mentioned as "Idolfried Ehrenberg - The Navigator Ido" in Revo's personal website in a list of characters related to the spin-off/parody story MoMoDaLoW. On the day of the release of Ido e Itaru Mori e Itaru Ido, Revo wrote the following message in his personal website, leaving its connection to Conquistadores open for speculation:
|How did General Cortés attain his own ship?
In this tumultous era, for a woman finding herself betwixt two forces, what did she gain and what did she lose?
And then, might the navigator Ido strive to arrive at "that forest" safe and sound before it came to the morning sail...
7th Story Märchen
He was officially featured as a narrator in 7th Story Märchen, appearing in Garasu no Hitsugi de Nemuru Himegimi, where his conversation with another man on a boat can be heard overlapped by Schneewittchen's narration after she awakens in the seven dwarves' home:
|- You! Who are you?
- My name is Idolfried Ehrenberg. Please feel free to call me Ido.
- Stop screwing around! Where's Cortés?
- I have no obligation to tell a fool like you.
- Shut it!
In the booklet of 7th Story Märchen, a message that reads "You might hear something that is not related to the actual story at some point" is found in the place of the quoted dialogue.
Idolfried's first live appearance was during the encore of the last Märchen Story Concert in Yokohama (January 15th, 2011), wherein he led the song Conquistadores. He reappeared during the 2011 live tour The Great Hope of the Territorial Revival with his own song, T·N·G! (Teinou ga!).
As equivocally implied by the aside in 7th Story Märchen, his leading of the song Conquistadores, and Revo's lines about him from his personal website, Idolfried could have been Hernán Cortés' navigator, or at least his compeer in the New World conquests.
|"My dad was a sailor,
But somehow he fell into a well and died."
Märchen von Friedhof reacts this way when he finds the heroine in the bottom of the well:
|"Oh, so you fell in as well?
This should be our first meeting,
so where is this strange familiarity coming from?"
This could mean both that Märchen von Friedhof, who has lost all of his memories, has a recollection of that girl as a familiar person stored in his mind -- and that the man who was a navigator and fell into a well is Idolfried Ehrenberg, the girl's father. The following lines from another point of the same song, which play with many double-readings of the word "Ido" in Japanese, hint that fact again:
|"Inside this well (Jap: Ido) that leads to another world (Jap: Ido)
I found a Man (lit. Ido) who embraced his Impulse (lit. Ido)"
Finally, assuming that Idolfried's body is in the bottom of a well, it could be reasonable to think that Märchen von Friedhof was "born" from the blend of März von Ludowing and Idolfried Ehrenberg's dead bodies. Below are the lines spoken in German by the "well" during Märchen von Friedhof's birth in Yoiyami no Uta. It sounds as though someone was persuading März von Ludowing, who just fell inside the well, to merge and create a new being:
|"I didn't want to die in a place like this
Boy, I can say the same for you, right?
Don't you still have things left to do on earth?
The time has come,
Come boy, now take me into yourself!"
Ido e Itaru Mori e Itaru Ido
The postcards released along with Ido e Itaru mori e Itaru Ido has certain difference(s) of colour in regards to its CD cover when it comes to the man who we would assume as Märchen von Friedhof. Their clothes' details mostly stay the same, though the postcards had the red buttons on his coat, the red chain button and the red clasps on his arm in stead of their golden counterparts in the CD cover (arguably, the golden streaks in the postcard and the white streaks in the CD cover can also second this). It could denote either that they are different from each other or even Idolfried's oblique existence in the single.
We also note that Hikari to Yami no Douwa's lyric was written in third person view, and it may be open to debate on who actually retold the whole story of März von Ludowing when Märchen von Friedhof in 7th Story Märchen could not recall who he was and what of his memoirs.
