The Majapahit kingdom did became a trading center at that time,and a lot of european country did reached indonesia and do some tradings with the majapahit kingdoms (sadly a lot of these records are lost in wars after the fall of majapahit), my speculation both of the routes are possible, but most possible route is to travel via silk road..funny thing is There's an Italian monk that reached indonesia that time around 1330, my assumption both route is viable (a safe but longer route via silk road, or shorter but more risky and dangerous route via red sea)
A bit spoiler and note- in the early conception of the story I give alvaro and ariella a group of bodyguards-mercenaries if I may say, to guarantee their safety, but got seperated after the incidents... These mercenaries might make their appearance later in the story (if they survived the storm) 😄
Should they make their appearance? What do you think??
