CHAPTER 17: AGAINST THE DEMON LORDS

In the culmination of Out of the Ab)'ss. the heroes
implemem Vizeran DeVir's scheme to take on the
demon lords. The arch mage's ritual draws the demon
lords together to fight to the death. leaving Demogorgon
victorious but weakened as the ad\·enturers face off
against the Prince of Demons. Even wounded and
weakened. though. Demogorgon is a legendary foe. and
the fate of the Undcrdark and all Facrun rests on the
adventurers' final battle.

READYING THE PLAN

Over the course of their adventures. the characters have
collected the components needed to create the talisman
at the cemer of Vizcran DeVir's summoning ritual:

The intact and unhatched egg of a purple worm (from

the worm hatchery in chapter 13)

• The ccntrnl eye of a beholder (from Karazikar in the
  Vast Oblivium in chapter 13, or some other source).
  Six feathers from six different angels (from the petri-
  fied angels in the Labyrinth in chapter 14)
  The heart of a goristro (from the demon slain by
  Yeenoghu in chapter 14)
  Thirteen tim mask~ sprouted from the footprint of a
  greater demon (from Araumycos's cavern in chapter
  16. or elsewhere)


• Gromph Bacnre's grimoire (from Sorcere
  in chapter 15)
  
  
  • A few drops of blood or ichor from a demon lord (from
    Yeenoghu's battle with the goristro in chapter 14. or
    from fightingjuiblex in chapter 16)
    After Vizeran DeVir uses these components to create
    the talisman known as the dark heart to draw forth
    the exiled demon lords from across the Underdark. he
    expects the adventurers to plant it in Mcnzoberranzan.
    Having learned from Vizeran's apprentice Grin Ousstyl
    of the arch mage's secret goal to sec the city destroyed.
    the characters might decide to place the dark heart
    talisman elsewhere. determining the battlefield for their
    confrontation with the demon lords (see "Let This Be
    Their Battlefield'').
  
  
  
  

ENACTING THE PLAN

Once the dark heart is in place, the ritual can begin.

The adventurers and their llllies take up a position not

far from the dark heart, close to where th<> demons will

appear. Where exactly depends on the placement of the

talisman and the advenlurers' own tactics and plans.

They can use a sending spell to signal Vizeran to begin

the ritual once the La lisman is in place. (If none of the

characters can cast sending, Vizeran can provide the

spell on a spell scroll). -----
