Separated!  Thalia helped us find the bridge Aeolus's castle floating 60 feet in the air but we were soon separated by the disolving bridge.  Thalia set out to find Hera her way, while we kept going to Aeolus to give him the winds and find out what else he knows.  He seemed like a nice guy but then went a little psycho and we gave him the storm spirits and got out of there after finding out that Piper's dad was being held by a giant named Encelaudaus on Mount Diablo, California.  So off we go on a side quest, Piper is my friend after all.
