Final Fantasy XII is the beggining of Ivalice story, thousand years in the past (compared to original Tactics), and it is located on Occuria. Then We have FFXII: Renevant Wings which takes places 2 years after XII. After that comes Final Fantasy Tactics A2 and then the last is Final Fantasy Tactics.

So Viera has always been there on Ivalice Story;

The world in Final Fantasy Tactics Advance is just an illusion created by the Grimoire, it is not the real Ivalice.
