Trying to finish the Russian demo

[monkeydog]

First of all, I'd like to say how awesome this game looks and plays. I played through KBL twice and enjoyed it very much. As far as the demo is concerned, I can't seem to finish my last quest. I have killed everything on the island, but I can't go through the door where the lizardmen are. I'm sure it has to do with completing the last quest, but I don't know what it says. I also visited eveyone on the isle as well. Does anyway have a translation of the objectives of these 6 or 7 quests that we are given in the demo? Any help would be greatly appreciated, as I would like to finish it.

Thanks!
