“If Lady Celica is going, then I shall go too. If you suffer any injuries whatsoever, allow me to heal them with my Recover spell.”
Genny (ジェニー Jenī lit. Jenny in the Japanese version; translated as Jeni in fan translations) is a playable character from Fire Emblem Gaiden. She is a Cleric that works at the same shrine that Celica has lived and trained at for years. When Celica decides to go on a journey to discover what is going wrong with their land, Genny pledges her healing skills to Celica and her group. She is somewhat lacking in self-confidence, claiming she can only fix minor injuries despite her great healing powers. After the war, she fell in love with one of her allies, although she refuses to specify who.
In Chapter 2, talk to her at the Novis Monastery.
When considering the two Clerics that are obtained at the beginning of each route, Genny can be thought of as the Cleric with a traditional defensive/healing support role, while Silque can be thought of as the Cleric with more offense oriented support spells.
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 spell 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 far easier since after learning Physic, 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.
Genny winds up with pretty good stats, but as with other Cleric type characters, she winds up with low HP and Defense. Her Speed is also on the low side. As long as you keep Genny well protected, she will fill her healer role wonderfully.
Both Genny and Silque are vital to their respective parties due to the unique spells they have.
Though no one could have possibly dreamed of it happening, it's said that she fell in love with one of her companions.
Who in the world could that person be? Her only answer is a smile.
“Lady Celica, I can't help you anymore. I'm sorry...”
