The Greek Warriors are the armored warriors from Ancient Greece. They are also located on other islands as well.
The soldiers protect the temple from which the Golden Vase was stolen. You must retrieve the vase from the Vikings' cave and return it to the soldiers, after which they will permit you to speak with the Oracle. A Greek soldier also appeared atop a Shark Tooth Island building as a promo earlier on when Time Tangled Island was just released. It was later removed after the island was released. The soldier returned in 2014 without explanation.
