What Am I? I'll tell you

Mouse to talon,
drought  
to  
ground land,
wealth  
impounded
 
Astute, astounding
and
astounded
 
confident,
confounded,
free and  
bound,
both
seen and shrouded,

I bleed,
am
phalanx
shield  
surrounded.
 
I am empty,
count it,
hope
people read what I left  
and try to write around it
profound,
lit, loud  
a twit
don't  
doubt it
