After a scolding from Dr. Kadowaki and teacher Quistis, Miss Trepe will ask Squall to go with her to the fire cavern. First, return to Squall's desk and use the computer terminal. Viewing the tutorial nets you your first two guardian forces: Quezacotl and Shiva. Now, leave the classroom and explore the halls of Balamb Garden - with your new friends in tow. Be sure to get the starter pack of cards from the man on the second floor walkway, meet with Seifer & Co. in the cafeteria, and pick up the rare Occult Fan magazine from the front end of the second library bookcase. Once you've seen the sights, meet Quistis at the central gate and head to the fire cavern, northeast of garden. source:
