I got to the quest involving Musa and I got to check his backstory and Vavra's self-lauded very well thought-out means to include Musa in the story. I was really interested what Vavra has come up with because a man from Mali in Bohemia seems inexplicable by any means. And, it's bad. I can't say I'm surprised at how bad it is, but it's really quite lazy.
Musa says he was useful to Bayazid, because at the time he was receiving envoys from "all over the world", "But soon after, we found ourselves at war with Timur and his golden horde". It's spelled with small letters, yes.
There are two problems here. For Musa to use the name "golden horde" is anachronistic for 1403, for one thing. For another, and more importantly, Musa is confusing the Golden Horde with the Timurid Empire, whose founder Tamerlane actually defeated his contemporary khan of the Golden Horde in a series of campaigns between 1386-1395. At least the minimum proof reading should have caught that.
Musa describes his decision to ask to be sent to Sigismund's court as means to free himself of Beyazid's court before what he saw as an inevitable fall of the Ottoman state in its war with Tamerlane (or the "Golden Horde" as Musa calls it). As he says himself "I did not want to wait for Timur's savages to cut my head off". Since the direct war between Tamerlane and Beyazid erupted in 1400, that is the earliest time when Musa could have asked to leave Beyazid's court. Still, he must have been a very keen strategist, or deeply pessimistic about Beyazid's chances, in order to look for refuge in Hungary this early. Beyazid was at the height of his power, having received the title Sultan of Anatolia a couple of years prior.
Musa managed to persuade Bayezid to send him to Hungary with Sigismund's messenger as a "goodwill gesture". As I wrote earlier in this thread, there is no evidence that Beyazid and Sigismund have ever been in contact, and the closest they ever were to each other was at the battle of Nicopolis. That Beyazid would make gestures of good will after mass executing prisoners of the Nicopolis, selling others into slavery, and ransoming those who were worth most, is very unlikely.
"It was around then" - Musa says, so this must be some time between 1400 and the battle of Ankara, on 20th July 1402 - "that Sigismund's messenger came to see the sultan". Four years after Nicopolis, Sigismund sends a messenger to Beyazid? What on Earth for? There were no diplomatic relations between the Ottoman state and any Christian states, and there would be for decades on.
"But let us say king Sigismund did not show me the respect that my position is worthy of". A bit vague, because what was his position? "Instead of making me his counsellor and physician he sent me here!"
Like I wrote all those pages back, in the pre-release thread, explaining Musa in Alexandria or Anatolia, or even in Adrianople is relatively easy, but explaining Musa in Bohemia is very, very difficult. But I can't say there was much effort put in it anyway.
