A Passage in the Dark

A hall of hollowed bone or ivory
Askew from time and space, and sightless seen,
A sudden shift between the world and me,
Another setting from some future scene,
There someone followed, someone walked ahead,
Although I could not see there mortal frame,
Did my ears mark the footsteps of the dead?
Should I have harkened further for their name?
Who waits within the passage in the dark?
Whose footsteps tread those halls of polished white?
Be they the lamb, or be they more the shark
That stalks beneath the waters of the night?
Be they a dreaded foe, or be they friend,
Be they whate’er, I’ll follow them again.
