Fll'Yissetat was a fairly powerful female green dragon who acted as an unwilling guardian for Abazigal's lair, having been geased into service. The key to unlocking the geas was a specific scroll kept elsewhere in Abazigal's lair.
In order to reach Abazigal, the player character in Baldur's Gate II: Throne of Bhaal will have to either release Fll'Yissetat, in which case she will simply leave, or fight her.
