@Cyclone They could grow larger as time passes and eventually just become unstable and rupture, creating two or more smaller elementals.
I was actually going to go for the opposite: they cannibalize one another to grow larger and more powerful. With greater size comes greater power and intelligence, so there is a clear hierarchy. The larger ones can even control their lessers to an extent in a way similar to how insects seem hiveminded.

I'd say you could contrive them not to be considered life by the white giants. In that case, they would be treated like weather events would. White giants might protect frightened creatures in their presence, but not know to actually attack the elementals.
Zephyrion wouldn't bother; it matters little seeing as even if they did kill a few, more would eventually just materialize to take the place of the dead. In a war between a finite number of white giants and infinite elementals, the elementals would slowly win if only by virtue of attrition. That being said, the air elementals aren't going to just go around killing everything in sight. Not unless they are told to do so
I just asked out of curiosity as to how a white giant might react to some sort of soulless, arguably nonliving
being just flying by. Would they even see it and sense its presence, or would they just interpret it as a gust of wind?
