You lived among the people of the Far Lands, a general term for places far
away and from which very few people arrived when the Blight came. The Far
Lands include outlying islands, the eastern continent, and places beyond
with which there has been little contact. There are hundreds of places that
Farlanders could have come from.
The ways of the Farlanders are not as well known to the people of Altheria,
and if you came from a small village, it is very possible that you might be
the last one who knows of your culture. With this option, you are free to
invent a culture and origin from which you hail, so long as its fits
comfortably within the world of Aelandris (speak with an Admin if you are
unsure).
Regardless of your origin, you completed a long journey to arrive in
Altheria, a place just as foreign to you as you seem to its residents, and
that journey and challenge of fitting in shapes your story.
