few years after the dust settled from the Fall, a small
team of prospectors from Venus discovered a Pandora
Gate. Now controlled by TerraGenesis, Caldwell was
used primarily for exoplanet research for several years,
though the hypercorp is now engaged in several alien
world terraforming and geo-engineering projects. Ter-
raGenesis regularly sells gate access to other hypercorps
and organizations. Caldwell is a remarkably smooth,
spindle-shaped asteroid about four kilometers long and
half a kilometer in diameter at its widest point. Called
the Vulcanoid Gate, it is situated at the bottom of a
deep crag near one of the asteroid’s narrow poles.
The closest planet to the sun has a mass comparable
to Luna but is a great deal denser due to its iron-nickel
core. Mercury rotates slowly and has no atmosphere,
so that its day side is hot enough to melt most metals,
while its night side is bitterly cold. Because it lacks
many of the elements needed for transhuman colonies
to be self-suf cient, Mercury is sparsely inhabited,
save for a handful of solar power relays, a few un-
derground mining stations, and a single large surface
mining concern, Cannon.
RESOURCES AND ECONOMICS
Most of Mercury’s economy is based on mining.
Iron, nickel, and other metals make up 70% of the
planet’s mass, making it the richest source of ferrous
metals outside of the asteroids. Mercury also does a
brisk business in relaying solar power and serves as a
jumping-off point for solar research concerns unwill-
ing or unable to support stations in the solar corona.
Mercury has limited Helium-3 deposits, although these
are predominantly mined for local use. It is an open
secret that several powers have antimatter production
stations here. Of cially, these stations are massive
solar power relays, but the immense toroid particle
accelerators and large spherical magnetic containment
units required for antimatter production and storage
are nearly impossible to disguise.
