Bahamutmas: The date of Bahamut’s birth, or perhaps the day of the birth of his first children with Tiamat. The chronicles are unclear and the dragons aren’t clarifying.
The Night of a Thousand Ravens: This is the night in which the Raven Queen herself sees to each of the dead personally, as her servants are given the night to their own pursuits. Ravens flock the streets, imitating people and stealing shiny bits. Angels with black wings are said to seek romances forbidden on any other night, leaving half-angel children who can talk to the dead in their wake.
I do love these toys.
