Swallowtail is a weekly Anomaly Hunt world boss in Neverness to Everness, encountered around Hethereau. It does not roam the open city — instead it presides over its own Anomalous Realm, "Let's Go See a Movie", filed by the Bureau under classification code Or-8251, which you step into to begin the hunt.
In terms of challenge, the Bureau rates the realm at Class IV difficulty, and it scales across difficulty tiers with a recommended band running from level 40 up to level 80. Each clear draws 60 stamina, so it is best slotted into a weekly run when you can spend the resin on the rewards.
Clearing Swallowtail pays out a loot pool of 4 rewards from its world boss table, headlined by the legendary Hunter Level EXP and Magic Thread. The full reward table with drop chances is listed below; tap any item to look it up in the catalogue.
The dossier below preserves the Monster Manual entry as it appears in game; the field notes that follow collect the rumors and sightings the Bureau logged before Swallowtail was formally catalogued, and the linked Anomaly case file holds the Bureau's full classification record.
