Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods [Stand-alone Story] Escape From Smalcatraz

I have unpacked your module, for learning purposes.

What I see in _Start KB section:
IF
GameEventSet("GAMEEVENT_GameStarted")
THEN
InitStory();
GoalCompleted;

What is InitStory() call? I see it for while, but dont understand what it is doing. Is it an engine call? Seems not, seems it is a custom procedure. Is it called from dependent Main mod or smth?

Would be great if you give some light for me on that.
