The map of Avalidad will be included in a upcoming sourcebook for Postcards from Avalidad, the Postcards Companion, which will also feature a timeline of events for the near future setting, optional rules* for Psionics, a more detailed city guide, information about other corporations of note, a list of equipment and a table of random encounters using cards, among other things.
*All the optional rules are meant for *Punk, the preferred set of mechanics for Postcards from Avalidad (though it includes statistics for Actual Fucking Monsters as well).
The inclusion of Avalidad’s map in the upcoming Postcards Companion will greatly enrich the immersive experience of the Postcards from Avalidad setting. The additional features like the timeline and detailed city guide are highly anticipated enhancements.
