A bit of digging reveals that FASA (which is back in play after many years) will be creating three other "Earth" style games to add to the Earthdawn (4th world) timeline. The tetrology of games will be: Earthrise, Earthdawn, Earthdusk, Earthfall. The first will be the age of dragons and their rule (rumor has it a player will be able to play a dragon, yes, a Shadowrun/Earthdawn power level dragon, take that as you will). The second is the 4th age of heroes we keep referencing. The third, Earthdusk, takes place after the time of Shadowrun during and just after the mana peak.
Wait, FASA is a thing again? GuhWHAHAUGH?
