- Centiket- Most similar to a human "second."
- Basic ket- One hundred "centikets." Roughly translated to a human hour.
- Decaket- Ten "kets." About a "half-day."
Kets started as something Anduin created in her head to describe how long it takes a Norn's egg to hatch. It was fully developed into a working system by the time she finished writing the first chapter of her story, The Youth of the Pykamain. See also tick.
