"Weh no Su" means, in the Canthan tongue, to be "Closer to the Stars". In order to defeat Shiro Tagachi, players must become Weh no Su, because only mortals who are enlighted this way are able to see, let alone fight Envoys from the immortal world. In order to be deemed worthy to be awarded Weh no Su status by the spirits of Cantha, the contestants must pass a test: In the Nahpui Quarter mission they must defeat four mighty "celestial" creatures and their minions.
