He's too dark?
At the end of some free-wheeling speculation over a fictional fantasy furry visual novel with a magical hotel set in a metaphysical labyrinth and a main character that can change appearance at will, the constraint that we want to fixate on is that Storm is too dark to maybe be distantly related to a mythical character?
Kopten, if I may call you that, I don't relish singling you out, but you just touched on a few things that can't be left unexamined.
One - and most importantly - any attempt to ligature race, ethnicity, and skin color to limited physical attributes of animals/anthropomorphic animals/androids/physical projections of A.I./an animated fucking toaster is inherently damaging and toxic and dangerous to members of the community, e.g. trying to treat fur color as a analogue to skin color. This is racial essentialism. This hurts all of us and limits us, but worst of all it singles out and excludes people of color in the furry community by attempting to remove agency from how they represent and explore themselves.
Two - maybe due to a misunderstanding or maybe a misapprehension of inherited traits I think it is worth pointing out that it is entirely possible for a white cow to be closely or directly related to a black cow. And, just so we're clear, it is also entirely possible for a dark skinned person to be directly related to a light skinned person. But, see point above, let this point go. Set it free. (Okay, also before I set it free, frequently the telling of these myths point out that the white cow is a meant to be a fated occurrence - a sign, omen, message, gift. Not herds of cattle of a certain color - okay those exist too sometimes in legend and myth like in some worship of Apis but not the point to take away from this.)
Three - I admit to leaving the door open on this one by playing fast, loose, and unscrupulous while discussing myth, so I'm going to state some things that I hope are obvious and maybe a couple less-obvious things too:
a) Myth ain't real! It may be honest, it may be revealing, and re-interpreting it can be liberating, but it's just a social construct meant to reify power through narrative. So don't think we owe mythic tradition anything, because people have been meddling with it for millennia. Most of the versions of myth we have been discussing are relatively late, often the most popular, traded and translated and retranslated again and again, and there are usually twenty other tellings, some of which omit whole characters or invent places and new plots. It matters whose telling it is. Whose translation. Whose edition of that same translation. There is no "true" version. No one true unifying myth or retelling (looking at you, Robert Graves). Actually, there've been many references to Ovid's Metamorphoses. Care to guess some of what Ovid is exploring? Myth! Power! Agency! Narrative mutability! In fact, if any of you have time, go read Ovid right now. You can read it in Latin or English with the translations side by side like the Loeb editions! Take and read!
b) While we were playing around trying to create as many concordances in the popular tradition of myth around Crete, Asterion, Io, Europa, Minos, and Pasiphaë, the endeavoring to draw that line from Io down to Storm through the migration of real ethnic groups is a great example of how myth is really used by nations and states to create arbitrary boundaries and in-groups. This can be another dangerous and misleading game meant to lend legitimacy to nationalism, ethnocentrism, and all kinds of trouble (read: fucked up shit.) Autochthony doesn't have to be alienating, and don't let me catch anybody trying to remove any kind of sovereignty from Indigenous peoples, but it as soon as it is used to enforce some kind of impossible ethnic homogeneity . . . And look, myth in all forms (oral tradition, religious tradition through text, etc.) are particularly important to diaspora communities, but when the interpreter of this story uses the myth to exclude those who don't resemble those in power currently shaping the mythic history, we land back at trouble (F.U.S.) So many nations do this or some derivative of it (I don't HAVE TIME today for discussing manifest destiny in these United States of America). SPEAKING OF MANIFEST DESTINY - another reading rec - revisit the Aeneid. In addition to many other things it is Roman propaganda reinforcing that the line of Roman monarchy wends back to Troy (its also kinda Augustan fanficiton). AND ALSO even in the microcosm of the Aegean basin diaspora in the is a constant! From the (many) Bronze Age depopulations, to the massive 1923 forced population exchange to the very current influx of migrants (who, by the way, are definitely being excluded in part using the exact apparatus we are discussing).
c) It's a fantasy! The authors have the license to take whatever liberties they desire! And so far they have not made any sort of indication that if Storm is meant to be coded Afro-Brazilian that they will use that against him. They could reveal anything they choose too about any character - Luke could be a literal physical manifestation of American patriotism (ala American Gods - also definitely not the point I am trying to make), Storm could be from folklore, the Olympians, an entirely novel manifestation of supernatural incident, or some Hittite deity, or just an ordinary man! I am not interested nor going to abide projection of casual, invented, racial limitations - intentional or unintentional.
Sorry y'all. I done rambled. And Kopten, you are not uniquely guilty of these things - but you just happened to land smack-dab in the middle of field in which I ruminate daily.
So, for your trouble, here's a shorter, neater response.
TL;DR
Don't try to enforce colorism, please, not in the world, not in furry fantasy, and let us take a long and uncomfortable look at ourselves when we are trying to so.
