DD:Restore Mardaneus' Sanity

Restore Mardaneus' Sanity is a Divine Divinity quest in Aleroth.

Objectives

Restore Mardaneus' sanity.
It seems that the healer Mardaneus may have been possessed by a demon. I must find out why this fellow behaves so strangely.

Unlock the entrance to the catacombs beneath Aleroth.
According to the elf, Lanilor, I must explore the catacombs beneath the village to find a cure for Mardaneus' odd behaviour. The entrance to the caverns lies near four statues. I have to move all four statues to the north in order to open the portal to the catacombs. Lanilor wanted me that evil creatures wander the caverns. I have a very bad feeling about this.

Help the dead necromancer.
Some friendly skeletons explained they are trying to rescue their dead master, a necromancer called Thelyron. They are using levers that are imbued with powerful magics, but something keeps going wrong. I have a feeling that if I can help them to resurrect Theylron, I may gain some information about Mardaneus.

Kill Thelyron.
It appears that the undead necromancer is the source of Mardaneus' obsession! He will not stop haunting the healer unless I kill him. Well, it may be a questionable task, but somebody has to do it.

Walkthrough

When the player character awakens and speaks with Joram, he informs them that their leader Mardaneus has gone "as crazy as a loon" and might be possessed by a demon. The player character can offer to meet with Mardaneus or put him out of his misery. If offering to meet Mardaneus, Joram directs the player character southwest to Mardaneus' house.

Upon exiting Joram's house, Lanilor can be found walking Mardaneus home. Mardaneus insists they must be vigilant because Nemesis is near. He states he could try to rest, if only the voice in his head would fall silent.

At the entrance of Mardaneus' house, Mardaneus has a vision of Lanilor as Thelyron Hashnitor, the demon lord of decay. He freezes Lanilor at his doorstep and locks himself in his house. Speaking with Lanilor initiates  Rescue Lanilor the Elf from his Icy Prison. It is still possible to complete Lanilor's quest and receive the quest rewards without speaking to him. Otherwise, Lanilor asks the player character to speak with Mardaneus to unfreeze him. If informing Lanilor that the front door is locked, he tells them to enter Mardaneus' house via a secret tunnel at the bottom of Aleroth well.

At the bottom of the well, there are passages sprawling out in several directions. Mardaneus' house is toward the southwest tunnel. A locked door bars the way to a ladder, but the key is on a crate next to the door. Upon entering Mardaneus' house, the player character can convince him to unfreeze Lanilor, who informs the player character about Aleroth catacombs.

The entrance to the catacombs must be unlocked. Northeast of Aleroth well, there are four dragon statues that can be rotated. Turning all statues to face north causes the centre statue to rise, revealing a path to the catacombs. Upon discovering the entrance, Lanilor rushes to the player character and offers a teleporter pyramid. This initiates  Find the Second Teleporter Pyramid.

If slaying Thelyron at the bottom of the catacombs, Mardaneus' sanity is restored. He teleports to the player character and creates a portal between the catacombs and Aleroth. He invites the player character to speak with him in town.

Notes
