Intervention quest

Intervention quests are special missions in World of Final Fantasy, available as early as Chapter 5, "The Champion Who Saved Grymoire". 
==Description==
By trading in two s to the Girl Who Forgot Her Name in the Girl's Tearoom, Lann and Reynn are able to battle unique Mirages and change the outcome of various events for the citizens of Grymoire.
During the quest, The Girl Who Forgot Her Name, a battle then begins with the twins, confused that they are in place of the warrior. The girl explains that they can redirect their friends destinies and lives by fighting in their most crucial battles, saying they can consider it helping them in secret.
Returning to the Girl's tearoom, she explains to the twins that everything that the twins accomplish on the souls behalf becomes that souls accomplishment, with the souls seeing the same battle as won by their own hand.
If the player completes every intervention quest (excluding "A Bridge's Woes") and purchases every Champion Medal, the player can purchase Ability Seeds from the Girl Who Forgot Her Name by trading in Arma Gems. If the player then finishes the postscript, a secret post-credits scene is unlocked, as well as three optional dungeons in The Girl's Tearoom, and prismariums of Lann and Reynn. In the Maxima update, Hauyn also becomes a playable character on the field alongside the twins.
The Maxima update adds three new intervention quests that are available after clearing the Postscript.
A listing of full synopses for each intervention quest can be found here.
A listing of battle dialogues for most intervention quest can also be found here.
If the player has not yet revived Tama by bringing the Kyubi's Souls to the Girl Who Forgot Her Name, Serafie takes the place of Tama in the battle dialogues of any intervention quests that involve the latter.
