Manual : There should be a CasterWin.odt and .html file in the game's main folder.
AI units on your continent :
The AI picks one "main action continent" at a time, and sends all their idle troops there. This time it seems to have picked yours.
As soon as they get a full stack of 9 (maybe 8) units and find no targets to attack, they should pick another continent unless there is no continent in the world left that's a valid target - that can happen when they are not at war with anyone and most lairs, nodes and neutral cities were already conquered. In that case they generally get stuck doing nothing until there is a war where they are needed.
