Since Valerian and Baldur weapons exist...

[Enkidoh]

Baldur is also a figure from Norse mythology and thus is ultimately meaningless as a 'Ogre-series' reference (the FF series freely takes names, and stories from real-world mythologies and religions around the world). But the Valerian reference is just that, an 'easter egg' style reference to another very influential game series (it should be noted a significant portion of Atlus's staff who worked on Ogre Battle and Tactics Ogre worked for Square on FF Tactics so this reference is even more intentional as fanservice, but not actually canonically linking the two games together as part of the same world.

As others have already stated, FFXIV is it's own unique world which is not part of any other fictional world, from the FF series or otherwise.

I gotta ask though, I think maybe the answer is obvious model recycling but Vanadiel goblins are in XIV are they going to be an MMO FF staple race now?

Well, considering the spoken races of FFXIV were directly based on the 'enlightened' races of Vana'diel from FFXI, it's probably just another fond callback to FFXI and not necessarily a 'staple race' (remember creatures called 'goblins' are a reoccurring FF monster race since the very first FF game, but with wildly differing appearances and natures).

Having said that though, I remember SE did once plan to feature a specific FF creature design as a deliberate reoccurring monster, in an attempt to make it a 'traditional' FF creature like chocobos and moogles - the FFXI mandragora. Despite like the goblin the mandragora was already a reoccurring enemy throughout the FF series, FFXI's specific mandragora design also appeared in FFXII thusly for this reason, however it seems this idea was later dropped as FFXIII did not feature them, although ARR does, but most likely for the above reason and not simply to re-establish an idea of making them a 'reoccurring monster design'.

But now I'm rambling again so I'll shut up now and let someone else speak.
