How to read it
Star, based here: a vendor, in the realm of the domain it leads with. The logo is the vendor's; the glow is what it leads with selling.
Outpost: a ring on a realm's edge for a vendor based elsewhere that also covers that domain. A lane runs home.
Moons: the other things it sells. Hollow while it is still expanding into them.
