I dont think Oma's have any temples do they, they're generally just outdoor monsters. Even the Ancient Oma's in PB were mainly outside.
Omas, Minos, and Woomas are 3 different species, and I always found it odd that WT had statues of Minos. Especially as WT was introduced in game several years before the Prajna patch and Mino's ever existed. Though, if I remember correctly the Minos were in the first Mir3 beta release where Prajna (Skeleton Island in Mir3) did exist from the start.
I expect there is full law of it all, but with Mir not being a western game its probably mostly lost in translation for us.
Wooma's are essentially minoturs though, no?
