Skulls for Mother is an off-screen companion adventure in Pillars of Eternity.
In-game description[ | ]
The pitch:
Somewhere in deep in the ruins of Ibrel's Well, a pair of pŵgra prey on travelers and offer up sacrifices to their "mother."
In the past, travelers simply knew to avoid all trails leading near the well, but in recent years, the pŵgra have increased the range of their hunts. Travelers have been abducted or killed on the roads between Solace Vale and Midwood.
Glanfathans are reticent to enter Ibrel's Well due to the religious significance of the ruins there, but that hasn't stopped the residents of the affected towns from requesting help from within the Dyrwood.
The conclusion:
[Companion Name] explored the ruins of Ibrel's Well extensively and found a wide array of dangers in the ancient city's crumbling homes and palaces.
Though the pŵgra had always been hostile to outsiders, [Companion Name] was able to speak with them and realized that they were being mentally controlled by someone else. The source of the increased attacks was an orlan cipher who had been disowned by her father and subsequently banished from the Twice-Split Arrows.
Especially skilled at mental domination, the cipher was using the pŵgra (her "children") to make a small fortune on unlucky travelers. However, once [Companion Name] drew her out into the open, the overconfident cipher was quickly defeated.
In the cipher's lair near the heart of Ibrel's Well, [Companion Name] discovered a grisly treasure: a necklace the pŵgra had formed from the teeth of the orlan's murdered father.
