Can I get some idea what happened at the end? I could not find Esher, tho' I did not plan to give the slate to him, so I just dropped the slate in the bubble and then I got to the end of the game.
I want to go back to my last save game and see what happens if I give it to Yeesha or Esher.

Hi,
If you want to see Esher, take the slate to Myst Isle through the Myst linking book back at the start. You will find Esher there.

Actually, the 'bad' Myst island ending is the best one. Strongly reccomended
