Also,  gods can not, generally speaking, be killed. EXCEPT by the deux a machina known as the Olympian Crystal. I am willing to accept that anything strong enough to kill a god might just be powerful enough to destroy magic.

But I also think that since this is just a shard from the crystal, it is not as powerful as the whole crystal. Hence the opportunity to severly wound but not destroy magic.
