Księga Czarodzieja (Book of the Sorcerer) - a Polish mod that adds factions.

I wonder if we can download models from posts dating back to 2016. The mod is still active; the latest screenshots were posted on the page on the 6th. What year are the files we're downloading from, and where does the link lead? I couldn't find this information on the page itself.

And the packs from the link don't contain much.
