What have I done wrong?"

“Following Sheeda's disturbing news, Marth suffered a terrible blow. Hardin was once a companion in battle, and an irreplaceable friend. "But why...? Why has he attacked Aritia?

There are Snipers in Jeorge's group. Do not attack them because they will kill you (Or worse, you'll kill Jeorge, who is essential). You cannot recruit Jeorge yet, wait until Chapter 8. Also it is essential that you have Julian start in the upperleft most starting space so that Julian can immediately talk to Rickard. The Village to the Northwest will give Marth a Hammerne staff.
Also be sure to send a cavalier or Pegasus knight after the thief holding the master seal. He flees the stage at around turn 5-6.
