The "Weeks of Balance" is not my doing.
You have 30 quests, that's all.
There are many achievements left. If you really want to know everything, you can open the map with an archiver and look into the file
Maps\SingleMissions\Sword and Sorcery 3\scripts\global\achievement_settings.lua
There, in the comments, it is described what each achievement is for and what it gives.
