Saviour's Rocks: Nocturne Integrity

Lifted verbatim from game files:
 * Player hitpoints for "Battle With An Avaricious Lorn-Fluke".
 * 5 Crew taken as collateral for 10 hit-points.
 * At 3 remaining, last-ditch option to ram the Lorn-Fluke opens for a 50/50 shot of dealing 3 points of damage.
 * If player still has 4 Nocturne Integrity after the battle, option unlocks to join the Tree of Ages against the Avaricious Lorn-Fluke.
 * After "The Tree of Ages", one crew member is returned for every 2 points remaining.
