Finally made it to the last tower at the Terrmian beach  parkour course!  Just FYI there's nothing at the end, but the satisfaction that you are completely crazy for even attempting it.  Although the last three towers do have chat interaction.  Much encouragement.  This was as fun as it was frustrating.

Have you done the quest line under Suggested "[Social Action] Forward Sweep & Discuss while Reading"?  If you like platforms, you'll like those quests : )

On my Termian 'To-Do' List!!!!!!!!
