Where Oh Where Art Thou....I've Now Been Seen A Time Or Two??

Is it possible
Can it be
That perhaps there's more
Than one of me
Sometimes I'm told we come as twins
One is no more
Now I begin
But to get to me
You'll dig through snow
In which direction did I go?
But be forwarned
You're fate is doom
My Protector ahead
Of me looms
With his guards
On either side
Man and beast
Both shall die.........
