Falrinth

After defeating him, you can check his journal, and it says the following:


 * Falrinth's Journal: This appears to be Falrinth's journal. Turning back a few pages, you start to read the wizard's most recent entries.
 * Falrinth's Journal: Again I have failed. I thought that surely the power of the Orb of Golden Death would be enough to free Zuggtmoy from her prison. Yet the magical wards still hold fast as they have for centuries.
 * Falrinth's Journal: There must be some other way.
 * You: Keep reading.
 * Falrinth's Journal: Very strange. Earlier today I detected a massive rupture in the planar membrane. And now the guards are reporting finding these Mysterious Remnants all throughout the Temple, as if they appeared out of nowhere.
 * Falrinth's Journal: The Remnants are infused with vast eldritch power ... and perhaps I can use that power for my own purposes. I shall have the guards bring me every Mysterious Remnant they find.
 * You: Keep reading.
 * Falrinth's Journal: Success! The guards have brought me not just Mysterious Remnants, but two large metallic pages infused with the same strange magic power.
 * Falrinth's Journal: By combining the power of one of the pages with the Orb, I have managed to remove the wards on the first three doors. The energy released in the process did some damage to the Temple, but a collapsed corridor or two is a small price to pay.
 * Falrinth's Journal: The last door must be opened by Zuggtmoy herself. I have travelled through the Elemental Nodes and given her the second Pages. It is now just a matter of hours until Zuggtmoy is free!
