Nope.
A question, do you know how that wiki works?
I do not and I have found a mistake. Tried to correct it but couldnt figure out how.
Anyway, under the lemma 'Dwemer history' the site says that some insight can be found in the book 'Azura and the box'.
This is not true.
'Azura and the box' is written by Marobar Sul.
He adapted folk tales commonly known in his surroundings and adapted them to give them a 'Dwemer feel'.
Those books have as much to do with Dwemer as Victorian books about foreign lands have to do with these foreign lands.
(Jungle book, Gullivers travels etc.)
"
Publisher's NoteI was reluctant to publish the works of Marobar Sul, but when the University of Gwylim Press asked me to edit this edition, I decided to use this as an opportunity to set the record straight once and for all.Scholars do not agree on the exact date of Marobar Sul's work, but it is generally agreed that they were written by the playwright "Gor Felim," famous for popular comedies and romances during the http://www.uesp.net/wiki/Lore:Interregnum between the fall of the First http://www.uesp.net/wiki/Lore:Cyrodiil Empire and the rise of http://www.uesp.net/wiki/Lore:Tiber_Septim. The current theory holds that Felim heard a few genuine http://www.uesp.net/wiki/Lore:Dwemer tales and adapted them to the stage in order to make money, along with rewritten versions of many of his own plays.Gor Felim created the persona of "Marobar Sul" who could translate the Dwemer language in order to add some sort of validity to the work and make it even more valuable to the gullible. Note that while "Marobar Sul" and http://www.uesp.net/wiki/Lore:Ancient_Tales_of_the_Dwemer became the subject of heated controversy, there are no reliable records of anyone actually meeting "Marobar Sul," nor was there anyone of that name employed by the http://www.uesp.net/wiki/Lore:Mages_Guild, the School of http://www.uesp.net/wiki/Lore:Julianos, or any other intellectual institution.In any case, the Dwemer in most of the tales of "Marobar Sul" bear little resemblance to the fearsome, unfathomable race that frightened even the Dunmer, Nords, and http://www.uesp.net/wiki/Lore:Redguard into submission and built ruins that even now have yet to be understood."Edit: On the 'calling':
The calling is radio technology.
In Morrowind you can find a lot of 'Dwemer coherers' in Dwemer ruins.
Coherers are a type of technology solely used in radio.
Kagrenac did not use the calling, it wasnt needed.
The fulfillment of his endeavor caused the souls of the Dwemer to be absorbed into Numidium.
Instantaneously, throughout Tamriel, even those in Skyrim and Hammerfell which (presumably) were not actively supporting (or even knew about) Kagrenac's plans.
Kagrenac struck the Heart (in panic and before he was ready), and all the Dwemer vanished, implying that the endeavor itself caused it, and it did not have to be coordinated via radio.
