"All warriors shall come to a crossroads, and there shall fate pass judgement."
The Crossroads are a site on an ancient protoss jungle world. First spoken of by Khas in sacred scriptures, it is said that "All true warriors will come to a place they do not expect to be and encounter those they did not expect to find. It is in that place the fate of the true warrior will be decided."
