ENVIRONMENTS

Contents

• Atmospheric Conditions - As with variants in gravity, a change in atmospheric conditions can cause major problems for characters.
• Corrosive Atmosphere - Some atmospheres (breathable or not) contain corrosive chemicals and gases.
• Decompression - The sudden decompression of a starship, vehicle, or other object can be dangerous to creatures inside.
• Table: Decompression Times
• Thick Atmosphere - Thick atmospheres are those that contain a more dense concentration of...
• Thin Atmosphere - Planets with thin atmospheres have less oxygen per breath than the standard Earth atmosphere.
• Toxic Atmosphere - Some atmospheres (breathable or not) contain toxic gases that are debilitating or lethal to some or all forms of life.
• Vacuum - Despite some popular myths, moving into a vacuum does not cause the body...
• Gravity - The force that gravity exerts on a person determines how they develop physically...
• Attack Roll Penalty - Creatures take a -2 penalty on attack rolls in a low-gravity environment...
• Carrying Capacity - A creature's normal carrying capacity is doubled in a low-gravity environment.
• Damage From Falling - Creatures do not fall as quickly in a low-gravity environment as they do in a normal- or high-gravity environment.
• High-Gravity Environments - In a high-gravity environment, the pull of gravity is significantly greater than that which we experience living on Earth.
• Long-Term Effects - Long-term exposure to low-gravity conditions can cause serious problems when returning to normal gravity.
• Low-Gravity Environments - In a low-gravity environment, the pull of gravity is significantly less than what we experience living on Earth.
• Modified Bull Rush Rules - A creature affected by a bull rush is pushed back 10 feet, plus 10 feet...
• Normal Gravity - " Normal gravity" equates to gravity on Earth. Environments with normal...
• Skill Check Bonuses - Creatures in a low-gravity environment gain a +10 bonus on Strength-based...
• Space Adaptation Syndrome - A creature exposed to weightlessness must make a Fortitude save (DC 15) to avoid the effects of space sickness.
• Speed - A creature's speed increases by +5 feet in a low-gravity environment.
• Weight Vs. Mass - While an object in zero gravity loses weight, it does not lose mass or momentum.
• Zero-Gravity Environments - Creatures in a zero-gravity environment can move enormously heavy objects.
• Radiation Sickness - Radiation can be naturally or artificially produced.
• Table: Radiation Exposure
• Table: Radiation Sickness
• Treating Radiation Sickness - Radiation sickness is considered a treatable disease that can be cured...
• Star Systems - A star system can contain one star or multiple stars.
• Black Dwarf Stars - Black dwarf stars completely burn out after expending their fuel.
• Black Holes - Black holes are stars that have expended their fuel sources and exploded in a massive supernova.
• Brown Dwarf Stars - In many ways, the brown dwarf is not even a star. Brown dwarf stars are...
• Degree Of Ionizing Radiation - Ionizing radiation-radiation that breaks down atoms within living tissue-is common in space.
• Hospitable Stars - The chief classifications of hospitable stars are F, G, and K.
• Inhospitable Stars - Class O, B, A, and M stars are the least likely to support planets capable of hosting human life.
• Neutron Stars - A neutron star is a large star that has exhausted its fuel source but hasn't collapsed in on itself.
• Number Of Planets - The number of planets in a given star system can be determined by rolling on Table: Star Systems.
• Red Supergiants - Most red supergiants begin their lives as average-sized stars.
• Star Type - Stars are classified using a lettering system that describes the star and gives information about its type.
• Table: Star Systems
• White Dwarf Stars - A white dwarf star is so much smaller than a neutron star that it does not have the mass to collapse in on itself.
• Stellar Hazards - Two types of stellar hazards can create higher-than-normal levels of ionizing radiation: solar flares and cosmic rays.
• Cosmic Rays - Cosmic rays, unlike solar flares, cannot be predicted.
• Solar Flares - Solar flares release tremendous amounts of electromagnetic energy (including...
