I know every grain of sand in the desert. Many of them by name.
The brave Desert Warrior is a true expert of the desert. He knows the location of every source of water hidden beneath its dunes, and can find his way through deadly swirling sandstorms that anyone else would find both impossible and impassible. He shrugs off scorching sun and scorpion’s sting alike, saying that he needs nothing more than his sword at his side to survive out there forever.
The Desert Warrior is always ready to plunge into unknown situations. This often sends him into the path of danger, but it can lead to great reward as well, like the time he discovered the cursed tomb of ancient Amset-Ra and battled a great stone scarab to win the forgotten pharaoh’s treasure. He also builds the most magnificent sand castles you’ve ever seen!
