“Yes. To prepare myself for battle, I visualize the enemy in front of me. Then, during battle, I can focus all my attention on them. If you want to survive this war, you must focus all your attention on the enemy.”
Garcia is a playable character in Fire Emblem: The Sacred Stones. He can be found in Chapter 2 of the game: The Protected. In the chapter, Bandits are attacking villages in the area of Ide and Garcia and his son narrowly escape their hometown to get away.
In the level, Eirika and her small group arrive with a mountain range separating them from Garcia and his injured son, Ross. It is suggested that the player sends Vanessa to fly over the mountain range and bring Ross over to so that he can be healed by Moulder and protected from further harm. Garcia can (usually) take care of himself. After Eirika talks to Ross, the player can use Vanessa to put Ross on the other side of the mountain so he can talk to Garcia. They do not need to recruit him in the chapter, however, as he will automatically join after the battle's conclusion.
