Mystery of the Expedition is a multi-stage side quest in Windrose that begins when the ghost of a Spanish sailor speaks at an ancient grave. The quest sends you across three biomes to find the remains of Juan de la Cosa's crew, then out to sea to a shipwreck near Tortuga. The frustrating part for most players is that after the first grave, the world map stops marking the rest.
Quest overview
| Field | Value |
|---|---|
| Quest type | Side quest |
| Stages | 3 |
| Region | Open sea, multi-biome |
| Recommended preparation | Mid-tier gear, healing potions, an active save point |
| Final reward | Broken Ancient Medallion |
| Key NPC | Ghost of Juan de la Cosa |
The quest opens when you trigger an ancient grave site, and the ghost of Juan de la Cosa narrates the fate of his expedition. The journal then asks you to find the remaining graves, but it does not place waypoints for them. That is intended behavior, not a bug.
Stage 1: Find the three Spanish graves
The three required graves belong to Esteban Vargas, Jaime Lopez, and Guillermo Sanchez. One spawns in each of the three tiered biomes — foothills, swamp, and coastal jungle — but the exact island within each biome is randomized per save. That randomization is why no compass arrow appears after the first interaction.
Two map signals do most of the work for you:
- Magnifying-glass icons. Ancient grave sites you have already discovered show a small magnifying-glass legend marker. Zoom in on the world map and sweep each biome for these icons.
- Unexplored "?" islands. If a biome has no magnifying-glass icon, you have not yet landed on the island that hosts its grave. Sail to every question-mark island in that biome and walk the interior to trigger discovery.
Each grave site spawns a tough guardian when you approach. The foothills location is commonly held by a two-star alpha wolf with a deep health pool, so come geared and stocked on healing potions. A weapon with lifesteal, like the Plague Pistol, makes the fight much more forgiving.
Once the wolf is down, interact with the grave to summon Juan de la Cosa. He recounts the story of the buried sailor, betrayal by Jaime Lopez, and a planned rendezvous with Columbus near "Turtle Island," which the journal eventually identifies as Tortuga.
How you know it worked: after the third grave interaction, the quest log checks off all three Spanish graves and updates to "Find the expedition ship," with a proper marker added to the map.
Stage 2: Sail to the wreck near Tortuga
With all three graves inspected, the journal sets a quest marker near Tortuga. Open the map, plot a course, and head out. A capable ship matters here — a Frigate handles the patrolling pirates along the route comfortably.
The wreck itself sits beached on a small, otherwise empty island at the marker. You will need to anchor offshore and swim in. Drowned enemies patrol the decks and the surrounding shoreline, so clear them before searching the hull.
Stage 3: Search the shipwreck
Board the ship and work toward the captain's quarters. The door is labeled "Decrepit Door" and must be broken down to enter. Inside, you find Juan de la Cosa's skeleton seated in the cabin, with the Broken Ancient Medallion on him.
Picking up the medallion closes the final stage and marks the side quest complete in the log.
Completion check: the Broken Ancient Medallion enters your inventory, the quest log updates to complete, and the journal adds a note linking the medallion to the one your father gave you before your first voyage, plus a reference to a faction Juan calls the Order.
Common reasons the quest stalls
| Symptom | Cause | Fix |
|---|---|---|
| No marker after the first grave | Intended — later graves are not auto-marked | Search ancient grave sites in each biome using the magnifying-glass icons |
| Only one or two magnifying-glass icons on the map | You have not landed on the island hosting the missing grave | Visit every "?" island in the biome that lacks an icon |
| Foothills grave seems unreachable | A two-star alpha wolf is guarding it | Bring healing potions and a lifesteal weapon, or level up further before engaging |
| Wreck marker found but nothing to loot | Drowned enemies are still active, blocking interaction | Clear the decks and the surrounding shoreline, then search again |
| Decrepit Door won't open | The door must be broken, not interacted with | Attack the door until it breaks to access Juan's quarters |
Reward and lore payoff
The Broken Ancient Medallion is the only guaranteed reward at the end of the chain. It currently functions as a narrative item — there is no confirmed crafting or combat use for it. Its value is the lore hook: the medallion mirrors the one your father handed you before your first voyage, suggesting both belonged to the same Order working against the undead.
If you want mechanical payoff from the run, the practical gains come from the side activity along the way. Clearing drowned enemies at the wreck, looting question-mark islands you visit hunting graves, and the Piastres and XP picked up in those biomes all add up. Each "?" island you clear also reveals more legend icons on your map, which makes future grave-related quests far easier to track.
The medallion handoff at the end of Mystery of the Expedition reads like a setup rather than a payoff. The Order, the priestess, and the medallions tied to your father's history are clearly seeds for a longer thread, so hold onto the item and expect it to matter in a future update.
