The Homeward Star is a constellation of stars. It is roughly triangular in shape.
The Homeward Star is culturally important to Rosie Beestinger and her family. It is used by her family, and possibly other Halflings, as a means to navigate.
It was revealed to be a delicious snack to our local vore entity known as the Sanguilith, the entity that K'thriss Drow'b has entered a pact with, and that each time K'thriss Drow'b uses one of the stars upon his cloak of stars, or whatever the fuck it's called, it consumes one of said stars.
