Thanks for going through the trouble of writing that down for me, that's really nice. However, I know that excerpt, but it fits my vision of the metaplanes only so far. To me, the Ares bug hunters encounter The Hive in this form because this is what they expect and want. They set out to wage a war against the insect spirits, trying to change the world through violence,and so the metaplanes reflect this by creating a violent environment. The hero in my story is suffering from feelings of alienation, so this is the aspect the metaplanes embody for him.
When dealing with magic in Shadowrun, I like to be as vague as possible in order to encompass both the hermetic and the shamanistic world view, so that neither one is essentially the one and only truth. Sticking to a subjective (magic) reality is the best way to do this, IMHO.
