The available races are Human, Elf, Dwarf, Halfling, Half-Elf, Half-Orc and Dragonborn. More information can be found here.
Other races may be available for play but this will need to be discussed.
Abilities should be generated using the standard array: 15, 14, 13, 12, 10, 8
I haven't read through all the backgrounds in the PHB but most should be acceptable. Otherwise I have written up some new Backgrounds.
