At the southwestern edge of the Felakgathar Mountains is a monolithic structure shaped like a maul with the business end resting on the ground. The maul head is 400' long and 280' wide and constructed of an otherworldly stone parted from the Endless Wall. The haft of the maul is made of lava stone that rises 360' skyward where it tapers to a point.
Built in the Dawn Era by construction units under Danzar-Khâl, this enormous structure is named in honor of Felân-Dûl, the top engineer who manged the construction. Not simply a monument to a great person, its primary purpose is to serve as an anchor in a line of defenses spanning the length of the Vhurghad Region into Malurn. This defensive network is the Felân-Akthûl.
At this northern point, ocean water is drawn into the Jetties where it is transformed into three rivulets of lava that merge, becoming the head of the great lava river Lyrmadis. After flowing along Felakgathar for a thousand miles, it ends at a massive edifice called Felân-Dûl. Here the molten lava strikes a shimmering wall of energy, transformed back into seawater.
Felân-Dûl has barely visible closed apertures all about its surface. In the Creation War these were used to launch missile fire and spray gouts of lava at attackers. After the war, the place was sealed up by Danzar-Khâl's security forces. There are no records of anyone getting into the place since it was locked up.
