The Ark isn't a list of rooms anymore. It's finally a map.
I've wanted you to actually see the station for a while: six sectors on a wheel, each biome, the gates, and whatever's waiting on the next stretch. You pick where the run goes, not just which card pops up after a fight.
Hover a sector and it lights up. Cross a gate and you're in.
Every node tells you what it is: fight, shop, rest, event, contract, mini-boss. Forget an icon? Open the legend. Hover something and the tooltip spells out the reward, the lock, or whether you've already been there.
Then there's the spin. You'll see Arca Reconfiguration nodes on the map (left/right arrows). Step on one and the next stretch rotates: your biome's rooms slide out, the neighbour's slide in. It's not a shortcut. You're mixing the map on purpose.
Those imported rooms are transgenic nodes. They glow green. A transgenic fight is a bit nastier (enemies +1 level) and winning pays extra: gold, a heal, max HP, or a transgenic face. If a shop comes through, it can sell those faces. Worth it… or it eats you. You decide when to spin.
If something's unclear, drop it in the comments, I read them.
