I assume, if you draw Riots as random event, and it's game ending condition is not fullfilled, it is discarded, right?
It does NOT stay in game and ends it on some future turn, in which the eighth trouble marker is placed?
That's right, either it ends the game or it gets discarded. No events have persistent effects; they all are resolved immediately when drawn.
