I really dislike mandating that anyone reads the Lore. However, as we're off to a rollicking start with threads and posting, I do strongly recommend that we all read or reread the following two documents. 

The reason that I'm making this recommendation is because both documents carry information that all of Aereth's indigenous folks would know some of the information in them. Like they'd know about the Shrouds, the Long Winters, the cycles of the rings around Gwydion (the planet Aereth orbits) waxing and waning, etc.
