This character list is currently very bare-boned. I will be expanding it in the future, but for now, hopefully this and the timeline will suffice.

The list for order of appearance has only the characters that had an physical part in the story, not the people that were mentioned only in passing (such as Mirianna Ohmsford - Par and Coll's mother). The one that has the characters organized in alphabetical order (by last name where possible) has all of them.
