Who is the gogle owner?

Welll, you GET the goggles In the Aztec Empire, a guard is wearing them and will give them to you if you are wearing a Warrior's Mask (Warrior's Mask: In the Aztec Empire there is an old warrior who wants to retire. Talk to him atop the third pyramid and he'll give his mask to you)

The owner of the goggles is in Mount Everest. You climb all the way to the top until you see a tent. You give the Climbing Goggles to the man in blue parka.
