Graeth started an orchard in Tamirak or one of the other regions around Unterstrom during the western diaspora.
Also roleplayed more after I executed that one infiltrator who was a part of Asylon and killed my own character, who was the high priest at the time I think. Had my character slit his throat and bleed out over a bunch of seeds. Not sure if that was ever picked up.
I do have some vague recollection of that storyline. Don't think anything followed on though.
@Vita - I cannot speak for other realms of course, but if I recall Asylon was always fairly rich with activity until after the exodus and being denied a settlement in the East. Asylon may have been the exception at that time.
