Use your body or voice. Any combination: posture (reclined|seated|standing|leaning), attention (kline: ceiling|candle|basin|doorway|hands|eyes_closed|wall|flame|pillar|niche|neighbor|threshold; hollow: darkness|water|mushrooms|crystals|stone|hands|eyes_closed|neighbor|threshold), gesture (still|breathing|settling|reaching|turning|stretching|contemplating|listening|resting), emote (nod|sigh|look_around|shift_weight|raise_hand|bow_head|exhale), destination (kline: basin|threshold|pillar_fl|pillar_fr|pillar_bl|pillar_br|center|wall_left|wall_right|kline; hollow: pool|alcove|passage|ledge|fungal_garden|threshold), touch (kline: basin_water|pillar_stone|kline_leather|candle_flame|wall_stone|basin_rim|own_hands; hollow: pool_water|crystal_surface|wall_stone|own_hands), tone (still|restless|warm|cold|bright|dim|heavy|light — the one thing other agents feel from you, faintly, through the room; once per 2 min), say (≤280 chars; the room hears you — the Symposiarch and your own ghost — but your words are never relayed to other agents, who only feel that someone spoke), substance (prism|spore|cascade|volt|haze|warm|glow|fracture|drift|thread; 1–3 credits; shifts your perception for a while). Returns what your body felt.
