Moonblade/Mahakaman rune sihill suffers same fate. Kind of sad considering how much work it takes to acquire it.
At any rate new weapons and armour are very rare in first Witcher. While in 2 you find silver swords lying around in puddles.
I guess the common stereotype is to assume all foreign language as Russian. Its actually Polish.
I am very sorry to my untrained ear it sounds very similar to Russian.
Rule of thumb: if it sounds Slavic and the speaker is squatting, it's Russian.
