Field Manual
Abydos
The first world beyond Earth. A desert under three moons, a pyramid with a gate inside, and a mine that was worked for naquadah long before anyone on Earth knew the word.

Getting there
Abydos has the same address in every world, and the DHD of Earth's buried gate still remembers it: open that DHD and dial it again from its memory. Any gate of your own can dial it too.
No extra crystal is needed for another world of the same galaxy. A wormhole to another world takes four times the usual energy, as any other world does; the buried gate's own Power Crystal pays for it.
The world
Dunes as far as you can see, never any rain, and outcrops of old rock the wind has laid bare, where naquadah lies thick near the surface. Of anything else there is little to dig: some coal and iron, no more.
A day lasts 36 hours, half as long again as Earth's, and three moons cross the night: Edfu, the largest, then ochre Dja'Net and small, pale Nuturo.
Camels and rabbits live on the dunes. Nothing hostile spawns on Abydos.

The Temple
Classified The hall of the gateclick to read

A hall lit by braziers, with a DHD before the gate. The DHD holds its own Power Crystal and a Memory Crystal that remembers Earth, so the way home is one press away.
Look at its point of origin: on Abydos the gate and the DHD show Abydos's own symbol, not Earth's. A DHD always shows the symbol of the world it stands on.
Classified The side roomclick to read

Off the hall lies a room of carved walls. Its far wall is a slab with a winged sun, and under it rows of cartouches: ovals each holding the six symbols of a gate address. Reading them comes in a coming release.
On the wall of the same room hangs a papyrus map in a frame.
The mine
Take the Papyrus Map from its frame and use it on Abydos: it unrolls into a map of the land round the naquadah mine, the mine marked with a red cross. Walk until your marker reaches the cross.
Classified What you find thereclick to read

An open pit cut in terraces deep into the rock, a cobbled road winding down round its ledges to the floor, a timber hoist still leaning over its rim. The miners are long gone, but naquadah still shows in the walls of the lower terraces, and more lies just behind them.
