You can see why, looking back.It was a very big shoe, completely slathered in crap.They had been hounded by mortal enemies from sun to sun, planet to planet, and were now stretched thin -- and they needed our help.And so our first bill came due. Skyrines like me were volunteered to pay the price. As always.These enemies were already inside our solar system and were moving to establish a beachhead, but not on Earth.On Mars.
