Forlorn Blood

 is an Ill Health card obtained in the Apostle Obsonate legacy and is key to achieving a major victory. It is given from Working with Duty and Delight at the beginning of the game, and then decays from Savorous Blood.

"My illness has come for me. If I survive, I must taste the blood of our Delight, and soon."

When is on the table, it drastically increases the likelihood of a special Season of Sickness (on top of regular Sickness events), which must be able to consume Health or Savorous Blood or it will kill you.

The Dream of the End
"I consume the little vial of blood, lie back, close my eyes. Tomorrow I will be stronger."

Dream with Delightful Blood to turn Forlorn Blood into Savorous Blood.
