Aiwass did not immediately head to Star Antimony but instead lingered in the Holy Nation for a few more days.
After all, Favna and Helquinn had just reunited, and separating them again right away would seem rather harsh. Helquinn hadn't even met his son yet.
Moreover, Favna personally requested this from Aiwass—because when she saw Helquinn's Dragon Lance had decayed to the point of being unusable, she decided to craft him a brand-new lance.
As a long-lived dragon, she had mastered some of the Dwarves' magus craftsmanship. This was the very reason she could forge equipment.
…As for the materials she planned to use, Aiwass remained in the dark.
But Aiwass's Mana Points could not sustain Helquinn's prolonged combat state. Therefore, aside from the meeting and reunion, Helquinn mostly remained in his travel state—one that consumed no mana.
However, Rhine seemed to prefer his father's ghostly horse form more than the spectral elf clad in silver armor.
