Ewyn moves cautiously over towards the bowl (his hands empty, since he had been preparing a spell), places his hand together in front of him and bows over them.
He then makes a slight "shoo-ing" gesture, as a way of asking the being to move back, away from the bowl. If it does move back, Ewyn will crouch down, pick up the bowl and back away (carefully) from the beings, towards the rest of our group with the bowl and speaking to his retainer.
"Creg, come get this bowl and give it a once over, will you? See if these things are edible if you can."
