The Jackal, the Mourner, the Ghost, and the Tree

These four entities
possessed time, the same;
their lone similarity
is that they share fame.

The jackal sprang loose
past his binds and his curse,
only to spend all he has
with the damned, from his purse.

The mourner fell limply
and lay flat on the ground,
but with all of his feelings
he's still tightly bound.

The ghost that is hovering
makes follie of what is,
yet out of the four
it's the past that's what's his.

The master of all
is the one known as tree,
pandemonium pronounced
he alone will still be.

So mayhem suggests
after all, we have spoke
all entities will fall,
all except for.....the oak.
