Dubin Clay

Dubin Clay is a dwarf located in the Magus Commerce Exchange of Dalaran. Accoring to Imindril Spearsong, he is stubborn.

During the purge of Dalaran, he was sitting on a rim at the entrance of the shop.

When Dalaran relocated above Deadwind Pass, he fought against invading demons. He doesn't appear on the Broken Isles.
