Getting a large volume of stuff from one place to another is tricky in Ars Magica, well tricky unless your group of wayward wizards has access to some darn heavy duty transportation magic.
This spell is an example of a powerful spell which might be used to teleport all sorts of items, animal herds, or people to or from the covenant. The use of the Target: Circle allows for larger volumes of mixed products to be sent, rather than individuals effects.
Mass Arcane Teleportation

Teleport the contents of the circle to the place of the AC.

In the saga our wizards have raised a new island far off the western coast of Spain and getting materials to and from the island is tougher than I first thought it would be. This spell assists that purpose.
Along with the spell itself a magical item with the same effect would be handy. This might allow non-wizards to assist with the coordination of moving gear around. I also think that creating a circle via a spell might be handy too, or having designated points marked with circles as way-points for transfer. They could be designed to be ten to fifteen paces in diameter, allowing for a large volume of material to be transferred at once.
Circle’s Keystone (ReAnAqCoHeTe50) – a large grey stone tile invested with as the Mass Arcane Teleportation spell above, altered for unlimited uses per day. The stone is set touching the rim of the circle to be targeted, the arcane connection is set in a small depression atop the stone, and then a command phrase is spoken to activate. In this way the stone is reusable at multiple sites.
