Forgive me if the question's been asked already, but can anyone tell me what the scale of the Siren planetary map is? Speaking of maps, would any Siren's Song GMs care to share or comment on their campaign maps? Did you expand it as you went along, like the campaign book suggests? Or did you map the surface in advance, already knowing where the competing factions and encounters would be?

Siren is about 50,000 km in circumference and the map is roughly 46 cm across, so that comes out to about 1086 km/cm.

Perhaps I should’ve asked this before, but does the map represent the entire planet? I notice a partially rendered landmass on the eastern side of the map that has no corresponding part on the western edge. Does the equator run through the centre of the map, or are we looking at the northern hemisphere?

The map does render the entire planet. The partially rendered landmass on the eastern edge is actually an error that slipped through production, but you could also play it up as an in-game anomaly – land that was there when the scan started on one side of the world, and gone when the scan next approached.
