D&D - Derro lore

[awa]

according to my advanced d&d
extra cruel particularly hate humans human slaves are given the worst tasks and used for "breeding"
derro live only to slowly and humiliatingly kill humans/ demi humans
and for the "perversion of knowledge to their own dark ends"

several days of sunlight is fatal
very group oriented hate being alone
don't worship gods led by "savants" who have a random selection of spells of varying level the savants are sorta worshiped by regular derro
don't care for gold other then it's monetary value and love magic items
every 20 years go to war to with all their neighbors which kills off their weakest members and serves to unites the group.
