Diplomatic action
In one of the fastest decisions of the Holy Order of Druids in recorded history, they quickly decided that there must be put a stop to the actions of the god only 2 years after the digging had begun. This action started by having several high-ranking members travel to the Wasteland of Li'minar and personally interfere with the gods.
The interference started by retaking the tunnels they could, but as the gods quickly dug new tunnels and continued to use those the druids could not block this proved ineffective. As such the druids began limiting supplies of food and equipment but this measure too, was far too late as enough craftsmen and magicians had already gathered to make up for the lost imports.
