Basilisk Games has released
the v1.05 patch for Eschalon II. With this patch you also get the add-on adventure The Secret of Fathamurk for free.
This add-on is for high-level characters of level 15 or more. You can go to this area at any time regardless of your level. More info on The Secret of Fathamurk can be found
here.
You can view all of the changes for the patch
here. If you bought the game through Steam, Impulse, Gamersgate or any of the others then you probably won't get the patch and add-on until at least Monday.
