You can take whatever you can carry, basically equivalent to what you can get on a flight: the clothes on your back, a backpack or ruck, and another bag (large duffel or even a rolling suitcase if you prefer). You can fill your pockets with anything, wear anything within reason (budget <$5,000), and take any piece of technology you choose. You can take precious stones or metals assuming they're within a reasonable budget, you can take any weapon you choose with the only restriction being that you have to carry whatever ammunition you bring. You can even bring an animal, including a horse or a dog, with the assumption that it's trained.

Because this is a fantasy world, you can assume you'll be involved in some epic quest soon after arriving.

No need to go into too much detail with this, though you're welcome to justify your selections.

A few important things I'd bring are:

-Small caliber handgun with a couple hundred rounds of loose ammunition and several extra magazines
-Binoculars
-Sunglasses
-Sturdy solar-powered watch
-Kevlar clothing
-Lighter with extra fuel
-Flashlight
-Small solar panel for charging flashlight
-Water bottle with filter and extra filters
-Decent boots and spare boot socks
