regio network

Would it be possible to access the magic realm via a regio network?

I always thought it was, being given that the network reaches an aura of 10.

Is it a given that the regio network reaches Aura 10? I hadn't thought so.

You're right, it is not a given.

I should have written "[...] if the network in question reaches an aura of 10.

I don't get it. All the gates to others Realms (Faery gates, Hell entrances...) have to bo in Regiones with Aura of 10 ?

Or may such a passage exist without any Regio ?
If a Realm's Entrance can stay without any Regio, why would a Regio require an Aura of 10 to have one ?
