In case you cannot read a thread's title properly, there shall be spoilers in this thread. The purpose of it is to ask where the heck can things be found and to answer any of those questions. Anything else is not welcomed, so keep your extra advice at home.

So ask where you can find Espers, weapons, accessories, monsters, rare game, magicks, technicks, etc...

I am looking for Ghosts! The Bestiary says that they can be found in the Garamsythe Waterway, but where?
