Just got sidetracked mildly by the holidays and some other reading (specifically, The Laundry rpg from Cubicle 7). I still have some tweaking to do on the character sheet and get back into the swing of adapting locations and whatnot from the Tribe 8 source books for the wiki.
However, reading The Laundry has gotten me thinking...what if the coming of the Z'bri is CASE NIGHTMARE GREEN? If the Laundryverse is the World Before, it puts a much more Lovecraftian spin on the entire setting. Synthesis would just be computational sorcery, basically using Dho-Na curves. This means that the Tribes have conquered being able to do the computations in their heads without turning their brain into boiled cabbage. It's probably not a crossover I would pursue, but it is an interesting exercise.
Otherwise, everyone have a good New Year and see you on the other side!
