The unobtainable dragon at the end of the World Tree
Astralym is Paldeck No. 204 and appears alongside Zenara in Palworld's final story boss encounter. Although it exists in the Pal data and therefore appears in search tools, the current game does not make Astralym available as a player-owned Pal.
Astralym is encountered with Zenara inside the Sealed Sanctum at the far end of the World Tree storyline. Reaching the battle requires late-game World Tree progression; it is a boss objective rather than a wild capture route.
Current Palworld 1.0 references agree that Astralym cannot be caught or produced by a verified parent combination. This guide therefore focuses on the encounter and current availability.
