What is the prophecy of blood in the underland chronicles?

In the Underland Chronicles, the Prophecy of Blood is the prophecy in the third book, "Gregor and the Curse of the Warmbloods". It goes like this (remember this is fake):

Warmblood now a blood born death,
will rob your body of it's breath,
mark you skin, and seal your fate.
The Underland becomes a plate.


Turn and turn and turn again.
You see the what but not the when.
Remedy and wrong entwine,
and so they form a single vine.


Bring the warrior from above
if yet his heart is swayed by love.
Bring the princess or despair,
no crawler cares without her there.


(repeat 2nd stanza)


Those whose blood runs red and hot
must join to seek the healing spot.
In the cradle find the cure,
for that which makes the blood impure.


(repeat 2nd stanza)


Gnawer, human, set aside
the hatreds that resides in side.
If the flames of war are fanned,
all warmbloods lose the Underland.


(repeat 2nd stanza)


this prophecy was written by Suzanne Collins.
