From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
Lord Octesian is one of the seven missing lords of Narnia who were exiled by King Miraz. The travelers on the Dawn Treader conclude that he died on Dragon Island in some way when they find a bracelet with his symbol on it among the dragon's treasures. (This is the bracelet that gets stuck on Eustace's arm when he turns into a dragon.) It's not clear whether Octesian was eaten by the dragon or whether, like Eustace, he himself was transformed into one.
