The Eventide is a district of southern Dalaran. It is also the location of the Dalaran Merchants' Bank and fountain, the latter which contains lucky coins thrown into the fountain by some of Azeroth's more influental figures.
Upon defeating Algalon the Observer in Ulduar and bringing to Rhonin in the Violet Citadel, the floating sculpture in the Eventide is used to transmit the code - signalling that all is well on Azeroth - to the Titans.

The sculpture has been remade as a statue of Dalaran's deceased leader, Rhonin. The Great Akazamzarak performs an ongoing (and loud) magic show in front of this statue.
