Alliance Faqs - How Do We Go About Completing A Delivery Special Quest?
A party needs to be at the designated place before contacting the GM; although Power Scrolls and Message Scrolls may be placed in an Alliance's scroll storeroom if appropriate.
Once the GM has been contacted and the party is in place, the item to be delivered is given to the party, plus a message to the Alliance contact that it has been done. The destination for the item will already have been given to the party in the Special Quest, so they can now proceed to the designated place.
If a return message is required they need to make sure they end their turn in the settlement. Once the GM has been contacted and a reply message sent to the Alliance contact that it has been done the party can go to the next destination, which is likely to be the settlement the Alliance HQ is in. Then the GM needs to be told that the party is in the settlement.
