While I was doing Va Fail Elaine preparations yesterday, I noticed yet again that Eskel said something about: "We had an excuse for why we didn't make new witchers before... but now we need to talk about this again. Later."
There's an obvious backdoor into the franchise, if prequels are off the table.
Sure, he's pretty much devastated after the Battle of Kaer Morhen and leaves the place, but there seems to be one witcher at least who realizes that they live in a world with hundreds of thousands of drowners, nekkers, ghouls and hundreds of draconids, relicts, spectres, insectoids, ogroids, etc etc behind every second corner. And that it might be a good idea if the witchers as monster fighters don't just die out, while the monsters keep breeding so vigorously.
Eskel also likes Korvir (because that's where the big money is being made), and all the sorcerors are in Korvir now; that's useful, since magic seems to be needed for the process, at least to some degree. Let's just pray that he won't chose that despicable Triss as a helping mage, since that'd pull him right into the annoying court intruiges that come bundled with that, but whatever.
Since Geralt is off to that Touissant holiday and to retire there with his Yen, since Lambert is off frolicking with his new ladyfriend, and since reinstating witchers is more than a 1 person job, he might have to arrange cooperation with survivors of other witcher schools (Letho! dude from Beast of Honorton! dude with manticore armor!), which might be really fun, and maybe open up more signs than just Axii, Aard, Quen, Igni, Yrden. Who knows what fancy signs the other schools teached.
The main character could either be Eskel or a next-gen witcher.
- Geralt, I am afraid, has retired.
- Lambert + Keira is a bit too similar to Geralt's adventures with his Yen. Might be fun to play in Lambert style, of course, but we can do that already (axii and those mad social skillz for dialogue choices ("hey, you retards! let us through or we'll beat you to pulp!"))
- Ciri would be dull and duller "THE CHOSEN ONE with SUPERHERO POWERS!"
- some random derp who turns into THE SAVIOUR and ARCHMAGE and MASTER THIEF and CHAMPION OF THE ARENA like in the Elderscrolls games is frigging annoying (that's the "custom character" option, right?)
