Diplomatic action
Since it was thought that the fey in their entirety was the will of Li'guth when the Holy Order of Druids learned of their predicament it was quickly debated if help should be sent. Eventually, they decided that they needed to send help to stay in agreement with Li'guth's will. Although their initial attempts at being mediators with the Unseelie fey, were not successful they soon decided to try to help open portals into the Faewild.
Despite their dislike of fey in general the Holy Order of Druids could not stand idly by while something created by the world tree stood to die. As such they decided to help in restoring the balance. This started by trying to mediate with the Unseelie fey. Unfortunately, even the druids were unable to scale the Wall of Li'guth and contact them, so they had to abandon their attempts. As they accepted the setback they started researching ways to make a new portal into the Faewild and restoring the Seelie fey by giving them another way to go home again. This research was arduous and took many centuries to complete. Fortunately most fey could live with the sickness far beyond this.
