I have cleared Sgaile Castle but can't find Habren. I do know I have two areas I can't get to: one is the gate near the gate to the Wheel of Time – I'm guessing Habren is past that gate? But also on the lower level of Sgaile, there's that pillar that if I touch it I will lose health, if I hit it nothing happens. I did read the wall note on "the pillar..." and tried all the combinations of levers nearby I could think of but nothing seems to lower the pillars near what seems (based on the map) like a teleport with a note on the wall next to it. Help?
