Garlean Third Eye Customization option

You might want to check what Reapers actually do again. And that entry is still not specific examples. Still waiting

It doesn't need anything specific though; it says point blank "Garleans have little inborn ability to manipulate their body's aether, however, and thius the arcane arts have ever eluded all but a few". All but a few by definition means there are some, however far and few between, that can use aether.

There is no reason why the PC couldn't be one of those rare few.

That said, the only reason it wouldn't make sense in the story is because when friendly Garleans are revealed (eg Cid) it is something of a thing. I wouldn't even call it a big thing.... but it IS a thing. Most of these people make a point to hide their eye when in Allied areas.

...and THAT said, the elegant solution has been presented: make a glamour and call it something like "Garlean 3rd Eye Disguise". This makes it a non-story thing that RPers can use and enjoy without impact on the plot. The main character actually being a Garlean in-story creates a lot of potential subplots and questions that become too specific... like why wouldn't a significant group rally around an extremely powerful Garlean to try to put them on the throne as the new ruler, post EW? They clearly need a leader, and the Eikon-Slayer is absolutely on a power level of other world leaders.
