I've always wondered about this, but never thought of making a board about it.

Now I am. xD Please answer this query of mine?

You need to complete an uncharted land map and get access to the uncharted island. There you can do Merena's quest to make a hydrus pet. It's like getting a galactic except she asks for spell items.

Oh, okay. Thank you for the explaination! Now I'm not so up in the clouds with wonder. @
