Like people said, he's probably about 100 or something similar. The way people talks about his tales aren't like talking to something recent. They sounds more like a saga like that of Achilles or so. But that's just the writer in me talking.

Btw, i think the witcher would only normally die of wounds and stuffs. It's not like he just gain the perk "immunity" and "regeneration" like that. His body got mutated and "immunity"+"regeneration" just happen to be on the surface. In reality, maybe his cell can renew themselves on periods o.o?
For all we knows, as years gone by, Geralt might live an immortal or maybe complete his mutation into something else. Witchers while almost invincible in tales aren't known for living very long thanks to their profession and extra works (and extra dangerous too since humans like Eilhart are even more lethal than monsters)

Well now, Geralt with all his wisdom, voice of tiered cynic and "I`m too old for this" stuff might give you impression that he saw Yaruga Landing and Conjunction of Spheres but it is not so.

He is certainly old for a man who does so much of buttbickin` but he was born circa 1210. Ergo he was 58 at the the time of Rivian Pogrom, and 63 at the time events of Witcher 2 take place.

Triss at this time must be 38 years old, and Yennifer - 99.

Ahem.. Last book of Witcher series was translated to Russian in 2001, so you see fans have a lot of time to compile more or less believable chronology, one I now referring to.

what, witchs are also immortal?
Where did those ugly old hag of a witch gone to !

Sorceresses have access to health and beauty treatments that the rest of us don't even have the right to dream of :) And they're competitive about it.

Normally, mere health and beautry treament doesnt make you still hot at the age of 99 >_>...Even Voldemort got ugly

Very true. Oldest mage was I think 500 years old. Frail-looking as anything, looked like he'd keel over at any time. He ended up dying of a heart attack too, I believe.

500 >_> I hope we dont see the day Geralt lives till the day they invent guns

he is also not really a traditional witcher right? he has extra procedures done that not many have had done right?

Bah! He just buffed himself to hell.

True, he was a cheating bastard.

begs the question of how he became so unmasterful in this game :P

but, as i was saying, no one knows the effects of what happened for all we know he could be able to live forever

According to the last book the story describes a fictive world during the time of WW2.
(Examples: Brenna = Stalingrad, Nilfgaard is Germany -> armies described as tank divisions and elves are shown as SS soldiers, There are also things like pogroms and mass expulsion mentioned)

In TW1, Geralt says that no witcher has ever died of old age. Since they live such dangerous lives, usually some monster gets them, sometime, but their life span IS greatly extended.

In the journal entry for Vesemir, it says that he's so old that he may even pre-date Kaer Morhen ... which means that he's very old indeed.

When Geralt says that he's "too old" for something or the other, I don't get the sense that he's talking about physical aging; it's more a weariness of the spirit. He's still in fabulous shape, physically, except for the scars. But after 100 years of seeing people treat each other badly, after 100 years of being an outcast, after 100 years of killing monster after monster, his zest for living is less than it was when he was young.

IIRC Sapkowski himself was against comparing Nilfgaard to Germany. In fact, German-sounding names are to be found in the North. Yennefer for example is from a city named Vengerberg.

I think that the Empire is more modeled after the Roman Empire. This of course does not relate to names or technology, but for example Nilfgaard is far more advanced than all the Northerners and is conquest-bound, autocratic as it is politically unstable. And it methods are just evergreen political ways of dealing with things.
