What happens to Prophecies guilds when Factions comes out?

[milias]

So what happens to Prophecies guilds when Factions comes out? What if some members have Factions and some don't? Can you move Prophecies guilds to Factions? Can they span both campaigns?

[Wandalf]

I suspect Guilds can span both campaigns, but I'm not really sure.

[Lord Valdrum]

If linked accounts you can travel back and forth, via the guild hall I think something like that. You'll be able to speak to the guild via both campaigns to for as much as I know as long as they're linked accounts you have to speak to the other guild.

[Zaxares]

I believe guild halls can span chapters. The members of a guild can be Prophecies-only, Factions-only, or both. Members of a guild are still restricted to visiting only the chapters they possess, so the only places all guild members can meet up is the Battle Isles or the Guild Hall.
