Ethereal Appearance

You make a circle of chalk with a candle at the north and south of the circle. With the sample you summon a floating image of a dead person. The person can answer questions and carry conversation but will withhold information about their death such as time, place, and the killers identity.  If the information is extracted, mentioned, or if the caster loses concentration before the duration because of outside forces, the image becomes an undead creature hostile towards all creature, including allies. The DM may make the decision of which creature it becomes.
