How many marker switches are in Myst?

Answer 1

There are 8 markers in total:

1. On the dock

2. In front of the observatory

3. At the spaceship

4. In the forest path at the birdbath

5. At the log cabin

6. At the large cog

7. At the woodshed

8. At the clock tower

Once you activate all markers, go back to the first marker and turn it off to reveal a secret note. At the end of the game, take this note to Atrus in D'ni or you will be trapped forever.
