Since we're into guild quests, let me jump on the band wagon and suggest race
guild quests!

Yes! Quests for race guilds are the secrets to hidden race powers and
bonuses. How does a minotaur learn to use its tail as a weapon or how a troll
learn to escape death are not always something that is complete innate at
birth. Perhaps they underwent some ritual or special training that some
members completed while not others. Perhaps the little sprite fell into a
pile of pixie dust as a baby and started to glow... who knows! There are
limitless ways to add/modify races to make each player unique. Best of all,
you can limit the number of quests to each player so that not everyone one can
have all the quests.

Each + to stats, power, skill, spell that are bonuses to each race can now be
made into a quest! Woo woo!
