“The shocking news brought by Caeda was a terrible blow to Marth. Hardin was once not only a comrade-in-arms, but a trusted confidant and irreplaceable friend. "Yet… why attack Altea? What have I done wrong?" Filled with frustration, Marth hurried his return to his homeland, but the first barrier stood in his way: Olbern Keep, headquarters of the Grustian Occupation Army led by the evil General Lang… also known as the "Nest of Evil."”

“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? What have I done wrong?" Filled with lament, Marth, before hurrying back to his homeland, was faced with his first challenge.

There is a secret shop in this stage on the tile between the vendor and the armory. All it contains is one Master Seal for 2500G. This is the first secret shop in the game, and can be accessed using the VIP Card obtained by recruiting or defeating Rickard.
In the original version of the game, the secret shop is on the northern edge of the map, 4 spaces east and 1 space north of the north-western house, and it sells all promotional items for 10000G each.

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.
