since i am well past the level where i can make use of this particular trainer, let me get sandava out of the way. this trainer offers quests to lower level adventuring dragons, and trades in forms for the rest of us.
this trainer is located in the floating crystal island of chiconis, in cave 4's lower level, to be precise. the way to the island has been covered elsewhere, but allow me to remind you how to get there.
go to the far right cave mouth, marked by the aquamarine colored crystal formation. head down the ramp and speak to sandava. if you are the proper level, the trainer will offer you some quests. as you can see, i am not of the proper level! ;-}
come back soon to get introduced to a trainer you will need to become familiar with, no matter what your level! see ya soon!
