THE SPIRE BRIDGE SWITCH, is above the 5th rune (need to learn the power of flight to get it). THE RUNE BRIDGE SWITCH is at the end of the SPIRE BRIDGE (a big blue line on your map). THE SWAN BRIDGE SWITCH is.....ok this one is a little hard too find.... do you see the 9th rune on top of the hill, down the right of the hill, a litle bit right of the treasure chest, you can see the switch. There is a secret cave that leads to it, the secret cave entrance is all the wat at the bottom of the hill YOU HAVE TO JUMP IN THE CORNER TO GET INSIDE. you might have a little trouble in the cave.
if you want the wings, you have to go near the sixth runestone and activate it, when you have white magic go a little bit left to the temple and sit on the medditating block and wait for the white magic to die.
you have to open the spire bridge to open the rune bridge, and if you want to open the spire bridge you have to learn the power of flight......if you want more comment. :D
