Myriad
A reef that grows across the map

The Myriad are a colonial reef organism. They grow, bud, and moult. Nothing is built; nothing is humanoid. Grubs root themselves into structures, and every unit hatches from a Cyst rooted in the mat.
Early play is cheap, fast, and swarm-heavy. Mid-game brings ranged spine fire and burrowed ambushes. Late game adds heavy ground beasts and flying threats. The mat spreads from Reefs and Polyps, and each creature carries an oversized organ set off to a side: bruise-violet to ink-black chitin, mauve tissue, ivory spines, and pink bloom nodes.
