Louisoix Leveilleur, Alphinaud and Alisaie's grandfather, is arguably coded to appear as Indian - and considering their father has darker skin as well, it's likely that they've just taken after their mother. And why can't Arenvald be Melanesian? Travanchet, an Ascian from 1.0 who makes a brief cameo in Heavensward as the instigator of the original summoning of Alexander?
Gaius van balesar, who's appearance looks similar to those of Indians with light/blue eyes. Aldis, who very clearly mimics the ideals of 90's Hispanics.
Dancing Wolf, Deep Canyon, Hanon Holyfist, Teledji Adeleji, Valiant Heart, Carvallain, Curious Georg, Wawalago Momolago, Jannequinard, Charibert, Grinnaux, Hermenost, Paulecrain, Ilberd, M;naago, Meffrid, Gundobald, Curtis, Conrad, Widargelt, Midnight Dew, EVERY DOMAN NATIVE, Tansui, Tista-Bie, Kai-Shirr, Olvara, Lakshmi, Jalzhan, Leofard, Nhaza'a, these are all PoC, and this list comprises of friend and foe EQUALLY. This list isn't even exhaustive, as this is a JAPANESE GAME, and as such there are going to be extremely light skinned characters that are meant to mimic East Asian cultures and appearances, and these are ALSO POC.
Wanting POC just for the sake of "representation" isn't representation, it's white-savior complex at its finest.
