Parson as a signomancer is oddly compelling, but there are three parts to hippiemancy: signomancy, flower power, and date-a-mancy. We've heard that time perception crumbles around flower power, but we don't know anything about date-a-mancy yet. This is a thing you use to get a date? Or more with time perception? Or dates like you eat?
When I think of hippies, I think of the weird plans and energy-saving devices from Mother Earth News circa 1970. Like a spinning wheel made from a bike, or a steam-powered car that runs on firewood. Which actually fits Parson pretty well--he's always coming up with a new, weird way of using what he finds in the world. Like losing battles to destroy siege, or linking a dirtmancer with a croakmancer to uncroak a volcano. Now if he'd just smoke a little weed, bathe in patchouli, start singing folk music, and grow his hair long to protest the war...yeah, Stanley would want to kill him.
