Archlords of the Realms
Siren the Amazon Exile
Girl meets girl and changes the fate of the world
Although there are plenty of other games set after Loren, there doesn’t seem to be any fleshing out of the Old War (not even flashbacks). Obviously, this wouldn’t be canon (not even the route that would lead to the events as in the standard timeline), so you could think of it as certain versions of the legend. As I couldn’t sell it anyway (just get a bit more attention for indie games), I wouldn’t have to worry about the legal ramifications of the engine I used. The likelihood I’d ever spend the time is, of course, low.
