Today I met a madman with astonishing magical powers. He told me he could help me locate anything in my realm if I solved his riddle.
So I asked him for the riddle and he said,"I am the little thing that goes forth alone, and comes back in a line with my brothers."
*I don't know the answer, but I can test any suggestions.
*The answer has nothing to do with the identity of the madman. *The answer is a 1 word answer.
