Usurpless

 

The supplanter has a land to possess
a kingdom of void,and unrest.

His eyes see
 enviable lands in the east.
(Needless and pristine)

Lands in dire need
send invitations from the west.
(Thinking a new king would be best)

The old tyrant has no interest.

   There's a name for a
  usurper,forced to rest
    in his mess...
   Useless.
