The Demecein Sect Fortress is the stronghold of about 20 Celestials in service to the god Heaglin. All that has been learned of it so far is that this is where Sirona trained as a Paladin of Heaglin and has lived a sheltered life, the fortress itself is within Petteese Creek and the reason for any sort of development there, and even though Sirona(and The Party) have limited access to things in the fortress as Sirona is very low ranking there, they do have access to a sleeping chamber with multiple bunks and it apparently has pleasant green painted walls and something akin to a fantasy disco ball that reflects light around the room because that's what Ceestials like, or so we're told.

The main contact for Sirona and The Party there is a person named Wuwwiw Ribunsin, a Cleric of Heaglin. They for the moment are the person who assigns quests and keeps tabs on what Sirona is up to. The rest of the Demicein Sect is there, somewhere in the Fortress or local area doing whatever it is they do, which presumably involves strengthening Heaglin and opposing Hayte and all things related such as activities of the nefarious The Cult Of Alden.

• Sirona and The Party reported a forest first in the Hylund Forest off to the east, mostly omitting that they are the ones that started it. They then left that for Wuwwiw to deal with.
• Wuwwiw tasked Sirona with delivering the magical construct known as Phulup¹⁾ to the bottom of the road leading up into Hayte Ridge. She was supposed to escort him there, send him on his way, and report back.
  • This did not go as planned because Sirona got curious and followed Phulup up the ridge only to find a Shrine Of Hayte there.
  • Sirona and The Party would later use a bomb and blow up part of the ridge to take out the shrine. This was not exactly what was asked of her. A shameful confession about this came out later to Wuwwiw.
• Sirona has been told her current and main task is just to figure out what Matilda is up to since it is now known that Matilda is in the region and likely headed to the Church Of Hayte.
