The Duty
From Oberon_wiki
The Duty is the term given by Elves to the tenets of the worship of the god, Corellon, who is said to have inspired the Elves and Gnomes to rise up against the tryrannical Eladrin masters in the Feywild, and to flee to Oberon.
As the name suggest 'the Duty' is a series of obligation upon the worshipper: it describes how Elves should behave towards family, friends, their race, other races, their religion, other religions and even (to a small extent) the Merebian Empire.
