One part that’s fun about writing is coming up with terms and sayings. Here’s a few from the Thordani.

• “May you rot” Thordani burn their dead on pyres; part of this is the belief that the body must be destroyed to free the spirit to go to the afterlife (the Infinite Sky being the Heaven analog). By saying “May you rot”, it is a desire that someone dies and their body is NOT burnt, delaying their departure to the afterlife until their remains are sufficiently reduced. And then presumably they don’t go to the Infinite Sky.
• “Heliospix” Translates literally as “Sun-watcher”, the official title of the high priestess (or priest sometimes) of Faenya, their patron deity. Serves as both mayor and religious leader in most villages.
• “Anapheos” Heroic title. Translates as “Dawn-Bringer”.
• “Kakos” A declaration of value of an individual, specifically that the individual is worthless and should be cut off entirely. Any effort given to them is wasted as there will be no reciprocating and they will be back for more later. Can be used as an edict by the priesthood to render an individual persona non grata. (The Thordani favor exile over straight execution for the worst offenses, though given the harshness of their environs the difference is often semantic.)
• “Remain in Shadow”
• “It would be better if your name was burnt from the scroll” Koiros, an owl deity of nature and the cycle of life is closely associated with Faenya. As the scribe of the Seldarine, one of his sacred items is a scroll that contains the names of every person on Oerth who has lived, is living, or will ever live. Saying one’s name should be burnt from the scroll is to say, “it would be better had you never existed”
• “Bonded” Equivalent to marriage between two individuals. Refers to the process by which a pair will bond feathers from their partner into their wing in place of their own, as a representation of the trust they have with each other and to symbolically represent them being two parts of a greater whole.
