A mysterious Arcane Forge has been added to Valdrakken in Patch 10.1.7.
The purpose of the game object remains unknown, perhaps it will be used by the Draenei when they unlock the Man’ari Eredar customization option?
The mysterious object is located near Crafting Order NPCs.
It’s even highlighted on the map of Valdrakken, which makes me think it will be used by all classes, not just the Draenei, but it’s definitely Draenei-themed.
