Honestly leveling up to 30+, getting Tharael and playing the Rhalata quest line sets you up to kiiiiinda be prepared for the main story's similar themes. Nessa left Tealor Arantheal waiting for her answer for literal months so she could at least start a life in Enderal first. She gets through the Golden Sickle, does bounty missions, explores Riverville and the Sun Coast before finally drinking enough to take on the Monster in the Arena.
And then everything you experience during the Rhalata quest with the Father mirrors the main story. Pride, hatred, obsession, unethical experimentation (not the Order itself, but Calia's father), body switching, dealing with the cruelty of the world and madness, finding that ONE person who understands you and dealing with them being taken away by the world (mirroring what happened to Yero and his wife, the Aged Man, Letho, Sirius, etc).
The trial during "Part of Something Momentous Part II" is a piece of cake for Nessa, who already knows of psionic illusions and the mind games that evil magic can play. Not much in Enderal tops what nightmares happened in the Rhalata's excavation site. Her and Tharael share that trauma and they have definitely talked through nightmares and ideas and psionics, they are probably more informed than the Order is since psionics and The Butcher of Ark are banned. A lot of Keepers and Novitiates seem ignorant of a lot of Enderal's darker secrets.
Aixon feels like someone the prophet once knew, rather than a total figment of your imagination. He represents the fear that holds you from escaping. You can pick up that skull at the end, "Regret," and instead of picking up the human heart or empty wine bottle at the altar you leave Regret on the stone that frees you. You leave Regret behind and it frees you. Nailaq left behind Qalian, Tharael left behind Brother Wrath. You kill Aixon, who represents fear and anxiety, and it frees you from the trial (I personally tried to kill him every time he opened his annoying mouth).
Then the High Ones meet the prophetess, and because you're level 30+ it's a sobering experience...for them. They may have brought the prophet back into this world, but like The Father and Tharael, you are fucked up because of it and stronger than you were. If Tharael can continue on, so can you.
Honestly having gone through the Rhalata quest and have Tharael by your side after is my favorite way to play. It adds a feeling of readiness instead of hopelessness at being called pathetic over and over again by the High Ones, who need to read a thesaurus and get more colorful words.
Nessa gives them the middle finger. How about you guys?
