The Centra Region is pretty barren, even of Draw points. The Centra Ruins are noteworthy, and you can enter them as soon as Balamb Garden becomes mobile. Other than that, the only Location of note is Edea's House.
There is one interesting bit to be found here: in the middle of several forests west of Edea's House, you'll find some rubble. Based on information from the Obel Lake creature, this seems to be a ruined village. However, there's nothing to actually find here.
