Fire Emblem: Shadow Dragon/Chapter 12

The Ageless Palace "The holy kingdom of Akaneia had come into being six centuries earlier, when the region's numerous city-states were unified under one monarch. The first king, Adrah, had fought valiantly to accomplish this, wielding the three weapons he came to call his regalia- gifts from the gods, some said. The kingdom Adrah forged was pronounced holy; its kings were esteemed. With Akaneia's aid, six more independent kingdoms sprang up in their own time. But Akaneia was always the greatest- and now, Marth was about to take his first walk through its historic palace's halls."

Begin
First things first, you will need to rush the prison if you hope to save all the hostages alive. Rush forward, don't leave any regrets behind. Send some weaker units to dispatch the two thieves on the side, and overall, don't leave your units in a discoordinated position, reinforcements will attack your rear. In fact, they appear at the beginning of Turn 3, so make sure your back is covered.

This map is easy after you save the prisoners, the rest of the enemies can be defeated with one or two good units, like a cavalier. There is free experience to the enemies that spawn outside. Good for leveling up lower level units.

Grab all the treasures, be sure to not miss the one outside to the right of the throne. Speaking of the throne, let's go to the boss...

This battle was a pushover, just seize the gate.

Save the game and let's go!
