Rules reference (condensed)
Turn. Reveal the top Journey card. A ♥ is a Refuge: take actions equal to its value (faces 10); each is Forage (draw) or Recover (slide any discard under the Supply deck). A ♠ is an Adversary: health = 2× rank index, attack = rank index (J/Q/K = 11/12/13).
Hide. If you encounter an Adversary of rank 2–10, you may attempt to Hide. First, nominate a card of rank 2–10 from your hand, then reveal the top card of the Supply deck. If the revealed card is lower than your nominated card, then Hiding succeeds (a tie fails). Either way, the revealed Supply card is returned to the bottom of the Supply deck. Success banks one bonus Forage or Regroup (no counter that time); but failure results in an Ambush: the Adversary strikes at once, then the round proceeds as normal.
Fighting. Each round: Strike with one card: a ♦ deals double its value (Bombardment), a ♣ its value. Or Regroup (play a ♣ to the discard, take any other discard into your satchel; no damage). Or Flee (discard one card; the Adversary is reshuffled into the Journey). Damage exactly equal to remaining health is a direct hit: bank Wreckage worth its attack. If it survives, cover its attack with card values and/or Wreckage, or you fall.
The Aces. A♥ the Destination (set aside; turn it when the Journey empties: you have arrived). A♠ the Nemesis: 40 health, 20 attack, cannot be fled. A♣ the Reckoning: free action in any fight, halve remaining health, once. A♦ the Revelation: strike for 20 flat; that round's counter −10. A♣/A♦ take no satchel room and count 0 if discarded.
Allies (optional). ♦/♣ faces trigger when played as your Strike: Jacks retrieve one same-suit card from the discard; Queens also reduce that round's counter by 5; Kings may rally as any rank 2–10 of their suit (♦ doubled).
Companions (optional). The first ♥ face joins after its refuge-10. Q the Partner: +1 hand limit. K the Witness: see the top Journey card. J the Burden: −1 limit, the group cannot flee; be rid of him via an Adversary (not the Nemesis): the flee discard plus one further card. Or discard 10♣ the Deliverance free at any time. Q/K may be spent as value 10 when covering; a companion who leaves is removed from the game.
