As Velisse approaches, she can see the movements of the knight don't seem natural. They remind her of a puppet on a string, as though something else is moving them in short jagged lurches. They stop when she speaks, and slowly turns to face her. She can hear the scrape of metal on metal as they turn. They doesn't speak, though.
The impression Velisse gets from them isn't of hostility though. They just seem lost or confused.
OOC:
Velisse can roll [Ins + Ins] to learn more, or just carry on talking to them.
