This is my first time playing this game and I am stuck at the Balacruf..

The answer to your first ? Is that in order to get the key to the tower of mana, go to hima and find clara from palamacosta (fogive me for slaughtering that word) and you'll go through a small miniclip where clara runs away and leaves the key. (ps, you should most likey beat the Balcraf Mausoleum) the second ? Is that you first need to go around the Mausoleum and light the torches and read the slabs. Find the one that tells you a color to a gem(on the west end of the Mausoleum) and grab a peice of paper and write down the gem to a color from the riddles in the other slabs in the order they tell you. Then go find the pedistal the changes the power of the Sorcerer's Ring(to a blast of air) then go tho the northern room by lighting each torchby the door and you will enter a room with a few fans of different colors. Hit them with the blasts of air from the Sorcerer's Ring in the order from the slabs you read eairer. You should use three combos of hiting the fans in a special order. The first two will crumble the walls from each side of the room, reveling a monster and a chest, and the last should open the northern door again and reveal the way to the seal. Your third ? Is that sheena joins your party a varity of ways. The first is if you find her in the chapel in the palamacosta region (a house of salvation) or if you find her after luin is destoryed in the fountain area.

Hope that helped
