There are no dragons on the Northeastern continent in the World of Ruin.
This is a translation error in the American version of the game. The
person on the Veldt which tips the party into this should have said
"dinosaurs," but in Japanese, the Kanji for dinosaurs can also be
applied to "fearful dragons," so the text was slightly mistranslated. As
far as we know, this is the only major translation error in the game.
If you do go to the forest on the Northeastern continent, you will find
some of the most difficult monsters in the game - Tyrannosaurs and
Brachiosaurs. Tyrannosaurs can cast Meteor and have a deadly bite, while
Brachiosaurs can use Ultima against you (!). You get a lot of
experience, though, if you emerge victorious.
