Further down a forest path will lead you to another stone gate. Like before a voice will tell you to defeat the nearby Dragon before you can proceed.
BOSS - Red Dragon- With more health than the Snow Dragon and fire magic instead of frost, this Dragon can be difficult to fell.
Go back to the second gate and continue forward. You'll fight through another couple of areas with enemies and start to see broken stone pillars among the trees. When you get to a four way crossroads, go up. Right leads you to a path that will circle back around to the left entrance again and going down returns you to the crossroads.
BOSS - Thunder Gigas- Similar to the Fire and Frost Gigas' but he uses Sylphid's spells to attack. A lot of health he will cast a devastating Thunderbolt if cornered.
BOSS - Blue Dragon- The Blue Dragon is Sylphid based, so like the Thunder Gigas. He has a lot of health, but less defense than the Thunder Gigas. He also has Blitz Breath.
The way is clear and the path opens to reveal the ancient Mana Tree. The creator of the Mana Sword in the ancient tales, the only weapon able to defeat the Mana Fortress. The Tree tells The Boy that he was destined to wield the sword. With the blessing and power of the Mana Tree, Dryad gains access to her full power and when the time comes will grant The Girl and The Sprite access to her Mana Sword Spells.
