There is a side door in Dalaran business district, and the second one enters the second floor. I don't know, you can ask the guards in Dalaran directly, and the mining trainer will have a red flag to indicate the location.

Dalaran is an area in the series of Warcraft games produced by Blizzard Entertainment. This country is a magic kingdom, and it is also famous as a magical country.

At first, it was a highly prosperous city, but later, because it did not listen to the advice of the guardian Medivh, it ignored the rise of the undead army. Its owner, antonidas, was killed by Arthas, and then Arthas and Kelgasud summoned Archimonde outside Dalaran, destroying Dalaran and never recovered.
