Into Eternal Night - Main quest | Forlorn Cliffs / Darklake District Walkthrough Sword Coast Legends Guide

The portal in Rhylfang's Lair takes you to Underdark. To get to the main city, you need to visit Forlorn Cliffs first and solve a riddle. After you gather your party, start exploring the abovementioned location. The riddle in question is in the Northern part (M11,Portal). After you interact with the pedestal, you learn that it is inactive and it is being protected with four seals. The seals can be activated using the pillars in the four corners (M11,1/2/3/4). If you zoom out camera view, you learn that next to the pedestals, there are symbols corresponding to each pillar. Your task is to turn the pillars in the way that makes the symbols on them face the pedestal and the symbols on the ground. After you complete that, return to the pedestal and the symbols on the ground. This way, you have just repaired portals all around Forlorn Cliffs and the will be no longer teleporting you to random locations. You now need to find Tezzarae's camp (M11,Tezzarae's Camp).

After you get there, search the camp. On Tezzarae's corpse, you find a journal (Tezzarae's Journal). Collect it and talk to Illydia. Meet your new ally. After the conversation with Izhkin, you can invite him into the party. Izhkin is a rogue. To make it over the pedestal, you require the magic stone hidden by Izhkin. To find it, leave the camp and go to another magic portal (M11,6).After you get there, you notice two more portals. The one that is the farthest away is the one to the Forlorn Cliffs (M11,6), and the one in the center takes you to there the magic stone is (M11,7). You find the stone at the corpse of Bolvisha (M11,8). After you collect the stone, you will be attacked by Umber Hulks. In themselves, the monsters are not too strong, but they cast a spell that eliminates you from the battle for a longer period of time. During the fight with them, keep your cleric away from the center. After you win, return to Tezzarae's camp and place the stone on the pedestal. This way, you open the portal to Underdark Descent. During the exploration, watch out for traps because they are plentiful here. A good idea is also to use Search and to collect Cave Moss, which you are going to need for the side quest with amulets, later on. Follow corridors of the cave and you will eventually reach the exit. Next to the exit, there is the corpse of a dwarf (M11,11), which you can loot for legendary axe half and a journal page. Reading the page activates side quest The Blood Debt.
