Monster Manual (Ragalla Supplement)
From D&D Wiki
 Monstrous Player Characters
Some monstrous individuals do not adhere to the savage ways of their people and embark out into the world to carve their own spot in it. These travelers may be heckled and lampooned all their days just for their race, and may find it hard to find work or friends. Players wishing to play such a race should speak with their Dungeon Master for both permission to do so, and discussion as to how the choice could effect the player.
