“I'm Silque, a priestess in the service of the goddess Mila. I was captured by bandits and brought to this shrine. Please, take me away from here.”
—Silque's Recruitment quote
Silque (シルク Shiruku, Silk in the Japanese version) is a playable character in Fire Emblem Gaiden. She is a sweet-tempered sister of Mila who was kidnapped by Thieves, who forced her into their Shrine. She is later rescued by Alm's group and becomes their healer. After the war, she headed to Rigel to heal the wounded.
Reach the end of the Thief Shrine on the world map. Silque will be in the last room, where you can talk with her to recruit her.
When considering the two Clerics that are obtained at the beginning of each route, Silque can be thought of as the Cleric with offense oriented support spells, while Genny plays a more traditional defensive/healing support role.
There are 3 key spells that differentiate Silque and Genny. The first is their Illusion spells. Genny's Illusion spell is learned at level 4 and will spawn Soldiers, fairly weak units that are mainly used as distractions or to weaken enemy units; while Silque's Illusion spell is learned at level 18 and spawns Dread Fighters, which are much more powerful.
The second spell that differentiates the two Clerics is Silque's Warp spell. Warp gives Silque the ability to send adjacent units to any location on the map, allowing for a greater range of strategies and flexibility.
The third ability that differentiates the two Clerics is Genny's Physic spell, which allows Genny to heal a unit anywhere on the map. This makes keeping units alive in Celica's route easier since Genny never has to put herself in danger to heal her allies. On Alm's route, Tatiana can be recruited near the end of the game with the Physic ability already learned.
In order to aid the injured, she headed towards Rigel.
“I'm sorry, everyone...”
