Walkthrough

 * Speak to the NPC near the entrance (Yvonne Lunet), then head down the ramp to the main corridor
 * Turn left and head North along the corridor - Halfway along the corridor turn left (West) into the Puzzle Room (A)
 * Solve the puzzle to activate the switches (take care to avoid connecting the trap tiles)
 * Use the Switch (B) in the Puzzle Room to activate the East Light Beam
 * Exit the puzzle room and use the Lever (C) opposite the door (in corridor, on pillar immediately to the South (right) of the opposite alcove) to turn the Mirror (D) on the ceiling
 * 1 pull of Lever (up or down) turns the Mirror by 45 degrees
 * Turn the Mirror until the light hits the Crystal (E) in one of the corners
 * Head round the corridor (south/anti-clockwise is quickest) and pull the Switches (B) on the South/East/North sides to activate the Light Beams
 * Nearby monsters must be killed to unlock the switches
 * Use the Lever (C) in each location to rotate the Mirror (D) and direct the Light Beam to the next Crystal (E)
 * Levers, Mirrors and Crystals are in the same locations relative to their Switch as they are for the West Light Beam
 * The Occulus is now open and the gate leading down to Eternity's Prison (F) unlocked. Continue round the corridor until reaching the doorway just to the North of the Puzzle Room
 * Head down the ramp to Eternity's Prison. Defeat the orange named Skeletal Warrior to gain entrance to Eternity's Prison
 * Beat Eternity down until the Yvonne shouts down to head back up to re-open the Occulus (~60% Health)
 * From time to time during the fight, Yvonne shouts to stand clear - run and hide behind one of the pillars in the Prison for protection (Eternity will not follow you)
 * Head back to the Puzzle Room (A) and re-solve the puzzle
 * Repeat the Switches (B) and Levers (C) to light all 4 Crystals (E) again
 * When first lit the beams all go clockwise. On the second pass it is fewer lever pulls to aim them counter-clockwise.  All that matters is that a beam terminates at each crystal.
 * During this phase, creatures emerge, surrounded by necromantic energy and dangerous to any who approach
 * The creatures are un-targettable un-named swirly skull-things of necromantic power that travel round the corridor during this phase (in both directions)
 * They can be avoided by hugging the edges of the corridor and diving into the alcoves
 * If touched, they cause damage and inflict a 5s Necromantic Slow effect
 * Once all 4 Crystals are lit (and the Occulus is open once more), head down the ramp to Eternity's Prison (F)
 * Beat Eternity down until dead
 * From time to time during the fight, Yvonne shouts to stand clear - run and hide behind one of the pillars in the Prison for protection (Eternity will not follow you) to protect against a massive AoE spell that Eternity casts (~300 dmg at Challenge Level 23).
 * Once dead, Eternity bows in defeat, bathed in the moonlight. The Spectral Dragon freezes in place as her magical bindings return. Eternity is a prisoner once more.
 * Loot the end chest
 * duration2       =
 * chest           = 1 (end chest)
