Elflings don’t need to sleep. Instead, they meditate deeply, remaining semiconscious, for 6 hours a day. (The Common word for such meditation is “trance.”) While meditating, you can dream after a fashion; such dreams are actually mental exercises that have become reflexive through years of practice. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

You can read, speak, and write Common, Elvish, and Halfling.
