Unavoidable Fate: Given the correct offerings,  the Geyser Lord will set you forth upon a heroic path that may be tragic, glorious or both. Roll on the following tables. Replace with your own entries as they are used up.

When you...

1. See the unfurling of the carnellion sail
2. Taste the 'Seeing Bark' 
3. Smell the crushed black poppies
4. Hear three eagles at midnight
5. Receive the gift of the spider 
6. Cause the saddest one to laugh
7. Die the little death
8. Are accused of the Lord's crime. 

You will...

1. Travel to the source of the great river.
2.  Journey to the Temple of Three Errors.
3. Journey to the Tree of the Lonely God.
4. Find the pool where the women go to drown.
5. Seek the counsel of the reptile oracle.
6. Travel to frozen Joten Lodge.
7. Go before the cracked temple.
8. Find the crimson pastures.

Once there,  you will be tasked to:

1. Marry the hideous Goblin Princess 
2. Poison the paladin Regent. 
3. Destroy the sad Golem called Tashok the Grinder
4. Murder the saintly children of the Duke.
5. Find the crown of delight.
6. Sack the temple of love.
7. Ruin the great artist's masterpiece.
8. Apprentice oneself to the Lonely archangel and steal his grimoire.

Upon accomplishing this, the character will achieve a dream appropriate to his/her character. This ought to be determined at the point of asking. There exists an 80% chance that the prophecy will end in the violent death of the character.  This will be expressed in pelucid fashion thusly:

1. Nothing that breathes will ever halt your assent. 
2. Beware the friend without blame.
3. As the Sun shines, so shall the glory be yours. 
4. The bride shamed, will be your damnation.
5. There shall be no curse more terrible than love.
6. Beneath the idol with your mother's face, sorrow will find you. 
7.  One final ascent beyond the clouds and you are gone. 
8.  In your dreams,  they will find you. 

The prophecies always come true unless the Geyser Lord is destroyed. If any result should see the character die before his/her destiny is  fulfilled, pass that death onto the most important NPC in that character's life. If there are none,  it's PC time. Everybody knows that the Geyser Lord's prophecies are inevitable.  It'll serve them right.

The actual lair of the Geyser Lord, is the boiling, underground vent. To challenge it here, one must be able to breathe water,  resist heat, resist poison  and resist extreme pressure. Needless to say,  it dwells within a hostile and alien environment. Without these precautions, expect to take 3d10 damage/round due to boiling water, make a DC-20 Constitution save to avoid gaining a level of fatigue each round due to the pressure and a further DC-15 Consitution  save/round to prevent nausea and 4d6 poison damage

Voice of Fate: Geyser Lord marks an opponent. Target must use their best attribute save (representing their heroic potential) to beat DC-18. Failure indicates that the character suffers disadvantage on all subsequent rolls until the Geyser Lord is slain or chooses to mark another character.
