I thought that at the beginning of the game, when you ask the advisor of Emyr about the situation, he explains that Vergen was easily conquerred. Still do wonder about Saskia though. When you meetI'm very glad to see a few more requests for the re-instatement of Dice Poker!
For myself, now that I've experienced a fair section of the game, I'm more curious than ever to know what became of Saskia and Vergen. I'd be very pleased if we could visit again, and see how things have developed or deteriorated there. (I'm rather surprised I've heard almost naught of them, so far.)
Rebuild Kaer Morhen. It seems when you get to level 20 you have some serious money. Let's spend it on something BIG. The whole area of Kaer Morhen could be returned to its former glory! We could relocate some of the refugees or give new homes to some of the displaced non-humans. We could even earn a living supplying witcher grade weapons for the onslaught of monsters that will happen later on in the game. For those desperate to create more switchers there could be an option to free a witcher trapped in a statue. Or have some scholars and mages come to Kaer Morhen to help discovering the old secrets? Perhaps even find a way of creating witchers with a better mortality rate? Also I really want somewhere I can display my cool mastercraft armour and weapons I have made possibly somewhere to hang my trophies too!
