The Cloud Universe globular cluster's eccentric orbit passes through dense clouds near the galactic center, gathering gas and dust which condense into heavy-metal-rich stars and planets.

Daven Laure and Graydal, having left Serieve, look into the Cloud Universe (see here and here) from an unusual planet (see here).
It will be difficult to find Graydal's home planet, Kirkasant, in the Cloud Universe but she says:
"'...you will find a way.' The mirth faded. It had never been strong. 'Won't you?' The reflection of clouded stars glistened on her faceplate like tears." (Flandry's Legacy, p. 756)
Laure cannot see Graydal's face behind the reflection in her face plate but that reflection, of the stars in the Cloud Universe, resembles tears.
