Will Monarchs or Vassals create chapter houses of existing factional orders (e.g. Knights of the Lion for Sarleon) if they lose the town/castle where said order is housed?
So for example Kingdom of Sarleon lose Sarleon but hold Marleons without a Knighthood chapter, will they create a Knights of the Lion chapter there eventually?
No. Monarchs will randomly create new chapters if they don't have any in their fiefs. For example, Ravenstern belongs to King Gregory and is the capital of Ravenstern. Yet, it only has 30% chance to have a Dragon chapter there (and before v3.9, he could create Falcons too). Which means that a lot of times, King Gregory starts without a chapter in his possession. As a result, I already saw Gregory with a Silvermist and also an Eventide chapter lately. Of course, all monarchs will still have factional KO knights as household troops no matter what, so they don't lose much even if they are chapterless.
