The La Voute is a service that was first featured in the 3.5 edition's on page 234 and again in the 4th edition's [[Eberron Campaign Guide (book)|Eberron Campaign Guide on page 219 under Guilde Bancaire. The La Voute system is used and run by Maison Kundarak banks and magically links all their vaults. This allows those who have rented the service the ability to deposit an item weighing up to 10lbs and magically withdraw it from any other Kundarak bank branch. The client and any delegated companion receive a word of access to use the vault.

This service costs 10gp per day. Members of Maison Kundarak receive a discount.
