Messages go out to all of the Magi that the council for the Oppidum at Hèviz tonight to decide various rules and guidelines for the Oppidum. most importantly, the casting of the Aegis of the Hearth is to be done tonight and the boundaries are to be set.
The Oppidum has various bells that are rung for various meanings. A large deep bell is used to call the council. It rings slowly for roughly 10-15 minutes to give everyone time to make it. The alarm bell is much smaller and noisier. Feel free to think up other bells to use for whatever signals you think the Oppidum needs.
