"It is no burden, Sam, and it is a standing offer." Growing up in circles made social creatures of Mages. There wasn't always room for them to sleep privately- having one for her charges to share, one for her to curl in come the predawn knowing that everyone is accounted for, safe, and rested? It's done wonders for what little sleep she's managed to hold for herself.

Sam may not have come from their circle, may not have lived what they lived- but he was a mage. And that made him one of hers by default. "It will be an hour or so yet. If you wish to sit up we could work on a focus drill? Something to get you started."
