Dunno why but the implanted tag caught my eye first time I read the book and I'm a little bit sad that the only stuff in the playbook using it is the Skinner's tattoo.
I know — there's dust and sand and shit and surgery is deadly nowadays, but hey, Angels and Savvyheads are weird and can manage stuff like that. Me, I'd like to throw in some high-tech compound somewhere on the map, a place with white plastic corridors running underneath the earth, with AI and nanostuff and shit, where the Battlebabe can be grafted a gauss rifle in her own left arm.
So anyway, people, did you use that damn tag for something other than Dune's tattoos and for what, pray tell ?
