Monsters
As a Game Master, your job is to adapt the monsters with the characters, thus you are to modify these informations. Other stats like Vitality and Speed should also be increased, and a good way to do so is to base yourself on the character's stats.

The Test
Although it's not the most original quest, it start well a campain or a character's life. Since all humans have a background, most of them will be part of a Garden or group. But to become an Esthar soldier or a Balamb SeeD, you need qualities and talents. The characters are to perform a test, like an assault or a mission of average importance and difficulty, in order to become a member.
Deep Sea Research Center
Those who played the video game probably remember this. On the very South West of the world, in the middle of the ocean, is an old research center built a long time ago by Centra civilisation and later used by Esthar Scientists. The base was destroyed near the years 3940, and never used afterward. The mission is to find the facility and discover why it was destroyed.
Esthar? Take the second street to the left then turn right...
With all that occured during the time of troubles, many rumors about Esthar ran all around the world. People from everywhere search for the city, for personal reasons or others. The characters may have to travel and find Esthar, or to escort someone there. On the other hand, someone from Esthar may have to travel the rest of the world to stop these rumors, or guide people to the wrong places.
The bite bugs nest
On the island of Balamb, it's summer time...but it ain't no funny summer. The bite bugs are abnormally actives, and they attack people and houses. They are literally invading Balamb island, and their number is unusually great. Well, it's almost like that every 5 years or so. The PCs (as Balamb students or SeeDs), are commited to solve the problem. They must find the nest, that lies in an ancient cavern in the northen mountains...The PCs are given a time bomb before their depart, so they can blow up the whole nest and put'em to rest(Before they have the chance to set the bomb, make'em fight with a Bite Bug "queen" that should be at least 10 lvls higher than the other Bite Bugs).
