The whole running around and finding people thing is getting pretty old. If Lethe can talk to the people in their dreams, why can't she send them a message now? I know it's still kind of fishy, but at this rate we have so many characters that getting into the Shadow Temple is going to be a nightmare.

As gecko said, it is pretty much just two people finding everyone. That can be remedied, I guess, to speed up the search but my earlier point still stands.
