Diablo II/Arcane Sanctuary

After destroying the ../Tainted Sun/ Altar on the second level of the Claw Viper Temple below the beyond the, upon returning to Lut Gholein you need to talk to Drognan to activate the fourth quest of this Act.

You then need to talk to Jerhyn, who should now be standing on the stairs outside his palace in the west corner of Lut Gholein:

If you talk to the guard Kaelan, standing by the entrance to the palace:

If you talk to anyone else before entering the palace or leaving Lut Gholein:

If you return before completing this quest:

Harem Level 1
The spiral staircase down from the palace takes you to the first level of the Harem, which is small and not populated. The spiral staircase in its northeast room takes you down to the east corner of the second level, while the straight stair in its southwest room takes you down to its west corner.

Harem Level 2
The second level of the Harem is randomly populated with three of the following five monster types: s, s, s, icy s and s.

The layout is always the same, square with a large central room surrounded by a corridor, with doors to rooms all around its perimeter. The stairs down from the first level are always in the east and west corners, while the staircase in the north corner spirals down to the east corner of the Palace Cellar, and that in the south corner spirals down to its west corner.

Palace Cellar Level 1
The first level of the Palace Cellar is similarly populated to the Harem above it, except its s are fiery.

Although the placement of rooms and doors is somewhat random, the layout is also always square with the stairs down from the Harem in the east and west corners, while the staircase in the north corner spirals down to the east corner of the second level, and that in the south corner spirals down to its west corner. There's also a waypoint to the north of the stairs in the south corner.

Palace Cellar Level 2
The second level is similarly populated to the first, except its s are poisonous. The layout is also similar, except there is no waypoint.

Palace Cellar Level 3
The third level is similarly populated to the first two, except its s are electric. While the layout is still square and somewhat random, the only exit is a portal in the central room, which may be guarded...

Fire Eye


Fire Eye always spawns in the north quadrant of the third level of the Palace Cellar, and sometimes does so in the central room, guarding the portal. You don't need to kill him, and can simply left click on the portal to activate it, allowing you to travel through it to the Arcane Sanctuary.

Arcane Sanctuary
There's a waypoint at the base of the stairs down from the portal that transported you here from the Palace Cellar. This is the central hub of the Arcane Sanctuary, which is randomly populated by s, Goatmen and s. There can also be s.

Four paths lead away from the waypoint, to the northeast, southeast, southwest and northwest: each path branches to form a figure eight, with a path midday down connecting the opposite sides, before the two branches converge on the far side to the waypoint, leading to a platform on which there are either chests, or a lectern on which can be found.

Unfortunately, there doesn't appear to be any trick to navigating to the lectern, regardless of direction or layout (normal, portals, normal stairs or Escheresque impossible stairs). Just pick a path and travel down one side of it, and if the platform at the end doesn't have the lectern then create a portal, return to town and take the waypoint back to the hub to pick a different path.

Horazon's Journal
It only becomes clear whether you've picked the right path at the very end: paths to chests are straight and lead to small square platforms, while that to the lectern twists and turns, and you must go up some stairs to a larger, more elaborate platform with pillared arches and glowing glyphs floating in the air along its northern edges. The lectern is guarded by the ../Summoner/ (to whose presence you'll be alerted as you approach), but you can simply ignore him and left click on Horazon's Journal to read it:

When you finish reading, a red portal opens to the (where the last waypoint of the Act is visible upon exiting the portal, to the north) and this quest is complete.

Atma only speaks the following if you talk to her first upon your return to Lut Gholein:
