Keen Senses. You have proficiency in the Perception skill, a trait that all people with elven ancestry share. Sleepless. Elves are unable to sleep. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. While meditating, you can dream after a fashion. After resting in this way, you gain the same benefits that other humanoids do from 8 hours of sleep. You cannot be magically put to sleep.
Languages. You speak the language of your culture, often Elvish and/or Common.
