Vote! Where should the travellers go after Kon-Tiki?  Mira & Teyus on Kon-Tiki.  Map

When the travellers were leaving the site of the Kon-Tiki, the great adventurer Thor Heyerdahl gave them a piece of wood.  Later on, when they were on Luctus velo, the map shone and gave them the following hint: 

"You can use me to write with". 

What does that mean? Where should they go next?
