Where can you find poison powder in Rune Factory?

(First generation.) Well, you need to start by befriending a monster. You can do this once you've obtained the friendship glove from Cecilia. (In one of her quests on the bulletin board.) After that make sure you have a barn. If you don't speak to Byron to build one. Now befriend a monster by stroking them with the friendship glove. (Second generation.) Next enter the inn on the bottom floor in the room to the right press a all over the room until Orland enters and gives you you striking march. Now make sure you have a library built in Alvarna Academy, then look in the bookshelves until you find inquisitive waltz. Take a monster out of the barn the enter Trieste forest. Kill all the monsters and the monster makers in Trieste forest mushroom patch. (Without your monster being killed!!) Then go to the spawn point and use inquisitive waltz. Keep going until you get poison powder. Make sure there is space in your backpack and you still have enough rune points to use inquisitive waltz.
