Thimble’s Episode 1 story begins before she appears. In the final seconds before his execution, Thjazi Fang asks Halandil to tell Thimble not to be scared. He begins another message for her, but the rope goes taut before he can finish it.
At that moment, Thimble is nowhere near the gallows. She had been responsible for preparing the magical glyph meant to free Thjazi and getting it into the rescue chain before his execution. The glyph never arrives.
Azune Nayar, Occtis Tachonis and Teor Pridesire eventually follow that missing link to the hidden rooms in the Tanners. The place has been violently ransacked. Beneath a grate in the floor they find Thimble unconscious, badly wounded and close to death, with one wing bent and her needle swords scattered away from her.
While her life hangs in the balance, Thimble remembers Tír Cruthú and the day the doors to Faerie closed. She remembers losing the inner connection to that realm and beginning to age. A life in which mortality had once seemed distant became finite.
Teor remembers her from before that change. He tears the grate out of the floor despite injuring himself and uses healing magic to pull her back from the edge of death.
Thimble wakes, sees the completed glyph beside her and immediately says she has to get to Thjazi. Only then does she learn that the execution is already over.
The news breaks through whatever urgency had kept her moving. Thimble realizes she never had the chance to say goodbye. When Azune tells her that Thjazi had been proud of her, she rejects the reassurance and blames herself because the glyph is still there.
Her account makes clear that she did not abandon the rescue. Thimble had nearly finished the glyph when masked people entered the hideout and attacked her. She completed it, held onto it and fell through the grate before the attackers could find her there. She was critically wounded before she could deliver it.
That surviving glyph changes the problem facing everyone in the room. Azune examines it and confirms that it carries the expected conjuration and illusion magic. Those are also the schools he detected on Thjazi at the gallows. Because the genuine glyph is still with Thimble, the magic Azune detected on Thjazi came from something else.
Kattigan Vale later reconstructs the violence. He estimates that about seven masked people entered the rooms and that three died before their numbers finally overwhelmed Thimble. Crow feathers among the evidence suggest a possible Crow Keeper connection, but Episode 1 does not establish who the attackers actually were.
The search also reveals another loss. A display case has been broken open and the Stone of Nightsong is gone. Thimble recognizes it as the object she and Thjazi had obtained on a recent adventure. She does not know who took it or whether the theft was the reason for the attack.
By the end of Episode 1, Thimble knows that the rescue did not fail because she chose not to act. She had finished her part and nearly died trying to carry it forward.
That does little to soften what she feels. Thjazi is gone, the glyph is still in her hands, the Stone is missing, and the people who found her have not been identified.
His final message to her—do not be scared—survives as one more unfinished piece of a life they had spent traveling side by side.
