Madain Sari is a location in the north of the Outer Continent in Final Fantasy IX. A village, where a Summoner tribe lived, was situated here, before it was destroyed by Garland.

Princess Garnet and Eiko are both Summoners who were born in Madain Sari. Garnet's real mother took her away when the village was destroyed. Eiko lived here alone with her Moogles, her only friends after her grandfather passed away, for a long time.

In the game it is stated that the people of Madain Sari used Summon Magic to study the planet, and they theorized that the Eidolons were the guardians of the planet. The theory goes that Eidolons were manifested from the collected belief in myths and legends. The "Eidolon Wall", with many engravings of Eidolons on the walls, survived the attack on the village.
