I mean yes... In keeping with the hilariously dubious quality of PD, one would be just fine with inserting Welsh as Welsh into the story. you have me there.
As for a Wikia page, having a 'Welsh' page for the express trivia of how Welsh is used in the story seems redundant, when it could simply go under a Triva heading in a 'Morkaeg' page. :P This same suggested Morkaeg page would also be able to more easily talk about the in-universe orgins as well as the RL orgins of the language, in one handy page.Â
Organization! Ease of Access! Me, pretending to have these skills and flaunt an IQ of doulbe what I really have!Â
