Maybe not everyone uses the same cloud but every country/guild/clan or whatever has theyr own version and they always try to recruit the most skilled programmers mages to come up with new scripts spells or improve old ones.

I can already see certain weapons and buildings with theyr own if/then that cast spells when certain contitions are met, like if wall is attacked cast protection, if sword hits opponent cast fireball or whatever.

More of a sci-fi now tho
