Multiverse Medieval — Universe 3/12: Lady Lily of House Bramble marries Sir Tomas of House Field in a 1424 castle great-hall with banners and torches; the multiverse cat acknowledges itself across timelines

A 3D BRIMSWORTH MULTIVERSE demo: Universe 3 of 12. The same R21 wedding cast reimagined as fae court — Lady Lily of House Bramble marries Sir Tomas of House Field in a stone CASTLE GREAT-HALL 500 years before the R23 1924 founding wedding. Banners hanging, torches flickering, long oaken tables, dais, stone arches, jousting yard outside in act 3. At t=300s a stone-archway portal glows; Bytes from cyberpunk universe walks through; meets local linen-collar castle-Bytes; both yawn and settle on a stone windowsill. Same C-E-G-C wedding leitmotif in LUTE + RECORDER + TABOR DRUM voicing. Like Camelot great-hall + The Princess Bride wedding + Studio Ghibli stone-and-torchlight warmth. ALL FICTIONAL.
