Answer:
I am the third from a sparkle bright, I thrive throughout the day and night. Deep in the path of a cows white drink. I've had thousands of millions of years to think. But one of my creatures is killing me. And so the question I ask to thee, is
I have a hundred legs, but cannot stand. I have a long neck, but no head. I cannot see. I'm neat and tidy as can be.
I have one eye. See near and far. I hold the moments you treasure and the things that make you weep.
My first is in wield, sever bones and marrow. My second is in blade, forged in cold steel. My third is an arbalest, and also in arrows. My fourth is in power, plunged through a shield. My fifth is in honor, and also in vows. My last will put an end to it all.
An open ended barrel, it is shaped like a hive. It is filled with the flesh, and the flesh is alive!
People take me on walks and I run and have fun. What am I?
