Blizzard Developers have always been known for their easter eggs and humor. The fountain located on the southwest of Dalaran, by the Alliance bank area, can be the source of some funny findings. You would require fishing tradeskill. These are at least eight of the coins you can find there from famous Warcraft characters: Aegwynn, Prince Arthas, King Terenas Menethil, Stalvan, Tirion Fordring, Alleria, and … Teron Gorefiend.
Teron? Yes, Teron. For those who played Warcraft II: Beyond the Dark Portal or have read World of Warcraft: Beyond the Dark Portal (pocket book), Teron Gorefiend was sent by Ner’zhul to Azeroth to retrieve three artifacts of power: the Scepter of Sargeras (Tomb of Sargeras), Book of Medivh (Alterac) and the Eye of Dalaran. Who would have known Teron would throw a wish coin on the fountain of Dalaran before departing with the black dragons? Thanks a bunch to Handclaw for providing these images.
Update: Ten additional coins have been found. Attumen the Huntsmen’s coin is hilarious. Check them out all 19 coins here.
