You learn that a third-generation charybdis is unable to fly due to its aetheric balance leaning strongly towards water.
Though the observer in charge wishes to revert the specimen and its kind, having deemed them a lost cause, Hermes is loath to give up on them, and offers to transform in order to guide the creature skyward. The proposal is met with shock and dismay, for transforming in public is considered vainglorious and unseemly.
While Hermes seems willing to bear the shame if it means saving the creatures, Emet-Selch is not wholly convinced. It is then that Hythlodaeus conceives of a solution. For this, he sends Emet-Selch off with the charybdis, while you and the others remain to assist him with the necessary preparations.
While the observer is impressed that the charybdis can in fact fly,
he remains of the opinion that it would be better to simply have their concept adjusted. Hermes, however, is adamant that they continue to be given a chance to prove themselves a worthy addition to the star, and his underling acquiesces before taking his leave. With that, Hermes declares all his present tasks complete, and you set off together back to Anagnorisis.
