The entities will respond when addressed, but aren't striking up conversations themselves. They will express thoughts related to the emotional aura they're carrying (an orb that creates sadness will talk about something sad, a peaceful orb will talk about something peaceful, etc) if asked what they want to say; if asked why they're there, they'll express confusion - they're not totally sure "why". They don't have answers about where they're from, and will be vague on the subject: they're from 'somewhere', or 'that place', but when asked to elaborate they won't have a name or description handy.
