A white-scaled dragon. Legendary, but almost never seen, for she is too shy.
History unknown. For the last few hundred years regularly performing for ‘the poor little people’. She became a legend in its own right, known by most children.
If you are a dragon and like people, that is a serious problem. The best solution may be to help from afar, letting them have at least some joy in their short lives.
Snowflake knows only one thing worth sharing: the joys of winter. So, whenever she wakes up, and there is not enough snow, she simply makes it.
Effect: in random intervals (let’s say 3d20 years), a random city or village will be visited by the mythical Snowflake. Be it summer or winter, a snowstorm comes and covers everything in knee-deep wonderful white. ;)
