Everyone thought the Martians had died. In a sense they had.
But they left behind seeds that grew into even more horrible monsters and caused waves of genetic mutations. It seemed the Earth would be overgrown by this new alien ecosystem.
Humans with knowledge of ancient magic and weird science desperately tried to use the salvaged Martian technologies to fight back this new threat.
Legends from every culture throughout the ages say there is another world.
An alternate world that is connected to Earth like a shadow.
A hidden realm made from the stuff of dreams and nightmares.
Most of the paths and gates to this world have been obscured or locked for millennia.
Now strange magic and arcane energies unleashed on Earth have spoiled and eroded many forgotten portals to this mystic world.
Creatures thought to exist only in folklore are stepping through...

STEP FOUR - Saving Throws
Record Saving Throws.
Basic Androids save as Dwarves.
All Mutant types save as Clerics.
All characters use Wisdom as Willpower for mental combat.
STEP FIVE - Power Points
Choose spells or roll for mutations as appropriate for character class.
The following rules replace the normal rules for spell memorization and mutation use:
Classes with powers, spells, mutations or psionics have a new score called power points, based on one of their attributes.
Cleric Points = WIS
Magic Points = INT
Mutant Points (Physical Mutations) = CON
Psionic Points (Mental Mutations) = CHA
When using a spell, mutation or psionic, roll a power throw with 2d10.
Success: If the power throw is equal to or less than current power points then the power works as written in the rules. Subtract 1 point from power points.
Failure: If the power throw is greater than current power points then power fails to work. Subtract 2 points from power points.
Backfire: If current power points are 8 or less, each time a power throw fails something bad happens.
Characters recover 1d4 power points per level every 12 hours.
Total power points cannot be greater than the ability score they are based upon.
STEP SIX - Hit Points
All first level characters roll Hit Points for their class and add their full Constitution score.
Any Constitution score modifiers to Hit Points are not factored in to this initial roll.
At each subsequent level characters roll additional Hit Points as usual for their class, including Constitution modifiers.
STEP SEVEN - Starting Funds
All characters roll 3d8x10 for starting gold pieces with which to buy equipment.
