What does the timer on some of the Choices mean?

That means you'd better make a decision fast as you've just landed on a Quick Time Event! If you ever see a timer near the choices, you'll only have until it runs out to pick one. Once the timer ends, a choice will be made for you, and all other choices will become unavailable. A choice will also be made for you if you try to refresh the page or leave and come back while a timer is active. 

You can use a Rewind Token to go back, and all choices will once again become available, but the timer will start over as well. Learn more about NC Tokens in the Kanrik Chronicles NC FAQ.
