Gold Edition of Heroes of Might and Magic V.

There's a mission or campaign (I'm not sure because I haven't played the mission) featuring Sarett (Fenning's apprentice) who has to deliver some kind of crystal to the city of Stonehelm. He is helped by Xana. I haven't played DM&M.
So, I don't know.

I understand... This stage wasn't revealed to us in DM&M. After the first tutorial mission, in which we actually find the crystal, the second mission begins, and we already approach the gates of Stonehelm.
If it's a campaign, that's good, but it's more likely a mission.
Tribes of the East for 200 rubles? That's outrageous! I went to the store today (the prices there are quite low), and the Gold Edition isn't available yet, but Tribes costs 350. Well, I'll wait a bit longer or check other stores. But the price is just shocking, at least for me. They sell pirated copies for that much money here!))

There's also a fan-made guide and a wheel for Tribes...
