The Umbra‑Aegis looks like a large, military‑grade parasol. When closed it resembles an ordinary over‑sized umbrella; when opened it forms a shallow dome (about the size of a patio umbrella) that can be held overhead or mounted on a collapsible pole. In your setting it’s prized by couriers, agents, and nightclub bouncers because it’s portable, dramatic, and visually disorienting when activated. Materials (fictional names — non‑technical) Aegisweave — a laminated, ceramic‑like composite with a shimmering iridescent finish. In fiction it’s credited with “absorbing and dispersing high‑velocity impacts.” It has a crunchy, glassy look along the ribs that glint in streetlight. Nullmesh — a lightweight lattice that sits behind the Aegisweave. In the story it’s described as catching and neutralizing shards and splinters after an impact. Sonic‑Lattice (aka Sonocloth) — a thin membrane layered under the canopy that can be “tuned” to emit counter‑phases or scatter incoming directed‑sound pulses. The cloth ripples faintly when active and gives off a low, musical hum most people feel more than hear. Hushrim edge — the umbrella’s rim is embedded with tiny serrations that refract and scatter acoustic waves, producing a subtle halo of sound diffraction that helps confuse sonic targeting. Tone/narrative note: none of those names correspond to real materials — treat them like props or magic tech. See more
