I concur with Manfred - it depends on the logic of the 'language' used. If the spell is a logical process, then yes, an alteration would stand out, but if it properly arcane and barely understood even by its best practitioners, then Trojans and worms should be able to hide in suitably complex spells.
Less sensitive material might be guarded with more innocuous magics woven into the text: Casting causes a wizardly mark to be placed on the caster, but visible only to those of the correct magical tradition: a warning that he cannot be trusted. Such would normally be used to identify disobedient apprentices that have experimented with material they are not yet approved to study.
graphein - to write
The spell includes another magic that is as nearly opposite in effect as possible or otherwise tends to cancel it out. For example, an illusion spell might be linked to a spell generating a cloud of fog.

The secondary magic is one that knocks the caster unconscious the third or fourth time that the main spell is cast. Because it takes several castings for the secondary effect to manifest, casters are likely to conclude that the spell is safe for use and then be caught by surprise.
Wonderful submission. It has built in drama. It is a place in motion with a timeline of events for you to interact with AND powerful forces in motion. A nice setting to find it all. Really a top notch location. Go to Comment
Barbarians! And fairly well written I must say. With sounds of wild animals, but strangely calm at the same time, they must be a strange sight indeed. The only thing I didn't like as much are the names of their gods (if you've ever seen the Asterix comic or movies you'll know why ;) ).
I have seen some of the Asterix comics, but the names actually came from Echo's Rangerspeak sub, with the -rix suffis being added, using it in the sense of -el being used in Christian names meaning 'of god' Go to Comment
The devil's wind. Explains why people become crazy. They are caught up in this wind which steals their sanity which in turn feeds the wind. The wind is a leftover from when the air elementals banded together in a mass army at one point to attack the True Gods. The wind is leftover of their attack route and on the anniversary of the battle the wind sweeps through causing the madness.
