Having been separated, you reunited with Koldar at the Many-Pointed Star. You then split up in order to travel to the Temple District, en route to which, Jacek was almost spotted by the city guard who had arrested him, but managed to run away without being detected.
You reconvened at the Temple of Thanatos, one of the Gods of Light, and underwent your initiation. This involved ritual baptism, and consuming a potion that gave you visions of your own deaths – and everyone else’s. The exception was Daechir, who saw nothing.
