An impossible relief from the sweltering heat, the Oasis sounds like the fevered dream of a dying traveler.  A cool, refreshing spring of water surrounded by palm trees is tucked away from prying eyes, with a single tent set up from a traveler long past.  A lost traveler may find themselves there in their time of need, their thirst slaked by the crisp and impossibly cool water.
Oasis, Desert
a genie from a lamp
a traveler long past
I am a traveler from a distant land. I carry large amounts of food with me. I am able to kill bandits with one move.
I have. I am near death and need help. Thank you for coming, Genie.  Yeah, lets get goinng already, what do you need from me? I have been traveling for days and though I have food, I have run out of water.  We are in an oasis, there is water everywhere young traveler. I must be delusional. I see no water.  It is all around that palm tree. It is cool and refreshing. Thank you, genie. How does one become a genie? An evil witch trapped me in here, it wasn't by choice.  Oh my! You are trapped? Can I help? No, it is an ancient curse that imprisons me here. I'm so very sorry. Why did she do that? Were you a nromal human before? Yes I was forever ago. She promised me eternal happiness. she lied.
