Sound the Horns

Sound the Horns is a recurrent event lasting 28 days that gives the player the opportunity to claim great rewards. It consists of two elements that both are meant to reward players for playing the game without introducing any additional activities that need to be completed.
=Sign in Rewards=
For every day the player logins, while the event is running, a new reward can be claimed. It is unclear at this point if these rewards will change during different runs of the event.

=Expeditions=
The major part of the event falls under the category referred to by the game as "Expedition". The player needs to complete several activities (quests), and in return they receive Expedition Medals. The medals can then be exchanged in the Expedition Store. Once again, it is unknown if all this will change in subsequent runs of the event.
Max to claim: 592
