Quest-record coordinate: 124, -524. Use the active save marker as the final navigation authority.
Quest chain / World Tree story gate
Start with the researcher, recover 4 named Echobones, craft the Echoing Flute, and capture Panthalus before continuing toward the World Tree.
Direct answer
Visit the Ancient Civilization Researcher on the Deserted Islet, collect Marine Echobone (124, -524), Silent Echobone (356, -110), Seafoam Echobone (-516, -549), Tidewind Echobone (-262, 486), craft the Echoing Flute from the Faded Schematic, then return to the researcher and search the shrine. The objective requires a capture before the story continues toward the World Tree.

Mission route / not a speedrun
This order follows the reviewed mission records. It does not claim to be a verified fastest route between objectives.
Visit the Ancient Civilization Researcher on the Deserted Islet and start the Panthalus mission.
Collect the four named Echobones from the giant remains. Use the documented quest coordinates below as references, while treating the active markers in your current save as authoritative.
Use the Faded Schematic to craft the Echoing Flute, then show it to the researcher.
Search the shrine, begin the encounter, and capture Panthalus rather than treating the objective as a simple defeat.
Report back to the researcher and continue the main mission sequence toward the World Tree.
Keep Panthalus available when the mission directs you to the World Tree entrance.
Map boundary: The current local Palpagos, Sunreach, and World Tree snapshots do not contain dedicated Panthalus or Echobone quest markers. The coordinates below are quest-record references and are not injected into the local atlas.
Capture preparation
The mission ends in a capture objective. Bring enough control and spheres to avoid turning the final damage window into a knockout.
Prepare endgame capture resources before triggering the shrine encounter.
Use mobility and elevation to clear wide Water attacks instead of holding a fixed firing lane.
Bring Electric damage for the Water matchup, while preserving enough control to stop before a knockout.
Treat this as a capture objective and story gate, not a timed farming route.
Can be ridden as a flying mount. Only one can be summoned at a base, where it patrols overhead and bombards intruders.
Evidence matrix
The mission order and Pal profile are cross-checked independently; no external coordinate has been injected into the local atlas.

Quest checks
Panthalus is a quest-bound Legendary encounter, not a normal wild spawn to farm from a permanent map point. Start with the Ancient Civilization Researcher on the Deserted Islet and follow the mission chain.
Collect Marine Echobone (124, -524), Silent Echobone (356, -110), Seafoam Echobone (-516, -549), Tidewind Echobone (-262, 486). These are quest-record references; follow the active mission markers in your current save rather than treating them as local atlas pins.
