By the way, Sophronia would ensure that the silver and other items had been secured, either kept with Josef for safekeeping, just asking for a receipt of items put into his care (to be shown to the council whenever she meets with them).
She has brought 75 pawns of vis, as well. 15 pawns of Creo, 15 pawns of Intellego, 15 pawns of Rego and 30 pawns of Vim. Since she hasn't yet signed the charter and taken a sanctum something of this sort should be possible. If not, then she'd take the items to the Mercere House and establish an account and receive a statement of account from them.
