I construct the hard leather grimoire, and fill in the materia(about a Wind materia I). But the quest was not complete, I dont have a idea about that. Annyone can tell me how I should do to finish it.

the quest title is :

Require: a materia-enhanced engraved hard leather grimoire

Description: You have been entrusted with the request of an arcanist, a man of whose name you are likely to remain ignorant should you be forced to rely on Guildmaster Severian's selective memory. Construct the materia-enhanced engraved hard leather grimoire and deliver it to your forgetful tutor. Yew logs, one of the materials required in the creation of the tome, must either be obtained through gathering, or purchased from the markets of the Sapphire Avenue Exchange. And should you wish for a more patient explanation on materia, Severian suggests that you would be better served traveling to the Bonfire in central Thanalan and visiting the camp of the goblin Mutamix.
