"Alzim, now that's a name! Leader of the Alten Mercenary Corps, master tactician, ex-general of the Cadmury Kingdom's forces, slayer of entire brigades, or perhaps most notable is he is a master Weilder. Sadly many of the young do not remember him."

In the middle of a desert in an oasis is a single prospering oak tree. Near the tree is a large pool of water. Drinking from the water is said to give you eternal life but really only extends your life for as long as you continue drinking from it. Those that have found it and left, have never found it again. Some search for it still.
