When writing fantasy, I attempt to avoid idioms and proverbs, especially more modern ones. However, I like to create idioms and proverbs with Damensea flair and use those every so often. These help give my world a different feel than ours. Here’s some of the idioms and proverbs of Damensea:

• basilisk never loses its spots, even when molting = people can’t change their personality (typically negative)
• busy as a melissa in summer = extremely busy
• can’t judge a girl by her glamour = don’t judge on appearance
• cool as an arctic elf = extremely calm
• curiosity killed the sprite = curiosity can be dangerous
• don’t count your faebirds before they hatch = don’t depend on something that has yet to happen
• don’t look a gift unicorn in the mouth = don’t be ungrateful for a gift
• don’t rouse sleeping dragons = leave things alone
• don’t torment firekittens unless you want to get burned = don’t be reckless
• early firebird gets the gold apple = being first improves the chances of success
• faebirds of a feather flock together = those with similar tastes congregate
• fit as a brownie = in good health
• if wishes were pegasi, beggars would fly = wishing doesn’t solve things
• no sense in crying for spilt unicorn water = futile to regret what cannot be changed
• Ormas wasn’t built in a day = great things require time
• proud as a mama roc = extremely proud
• rarer than a faebird’s teeth = extremely rare
• steal someone’s cantrip = take undue credit
• when naga fly = something that will never happen
