Dara is an old woman of Caer Pelyn and is implied to be the leader of the village. Over 100 years in age, she is wise and very knowledgeable on the history of Caer Pelyn, and maintains that the Great Dragon, not a human, was the one who led the Five Heroes to victory against the Demon King many years ago. She is Saleh's grandmother and is first seen in Chapter 12 of Eirika's journey, at the end of the chapter, as the group takes shelter with Dara in Caer Pelyn. Saleh's supports with Myrrh reveal that she was saved by the Great Dragon as a child after monsters attacked the village.
By looking into the game's data, one can find unused character data for her. Her starting stats are very low; in fact, she has no stat additions and thus only uses the Druid base stats, which are added to character base stats to achieve a character's starting stats. She has growth rates that are identical to other NPCs; Mansel and Klimt among others. One interesting thing to note is that though she is obviously female, her in-game data shows her as a male Druid.
Based on her portrait, the clothing and headwear she wears are extremely similar to Saleh's.
