Circle of Zul'bor

You create a stationary, magical circle with a 10-foot-radius around yourself that allows creatures within to contact the spirits of their ancestors. For the duration, creatures of your choice within the circle can use an action to attempt to summon a spiritual visage of any deceased person they are descended from by speaking their chosen ancestor's name aloud. If the ancestor's soul is free and willing, it appears within the circle as an intangible, invulnerable spirit. The spirit can only see and hear within the circle, and it can't leave the circle unless it dismisses itself or the spell ends. The spirit is not under any obligation to act a certain way or even regard its descendant as being a relative, and it can choose to dismiss itself at any time for the duration of the spell. The magical circle lasts until you leave it or if it is dismissed by other magical means.
