Character Histories - Origins from across the rift or only this side?

I doubt I'll have a history in time for the event and frankly I think its better to not write anything extensive till I learn more about the game, the histories, etc. I'm doing so now, but I'm curious if we are limited to having our origin since the rift to being from this side (and if long enough lived, one of those caught on this side since) or if maybe we might be someone who has recently come from across the other side, from the old world. I'm not sure if this is what I intend to do, even if allowed, but it would explain much about how little I know of the town and people for roleplay purposes. Just brainstorming, so curious about the possibility.

Thanks!

Perfect, explains just what I needed to know. Thanks so much.
