Geyrun

'This is a bereft pet of Geyrun', on the puppy's card in the Nothing (B4 ch. 29); 'Geyrun was murdered. Find out who did it and why', with one clue — the obvious suspect was in council (B4 ch. 32).

An open quest only: Emberus's 'Find Out Who Killed My Son' gains a new objective — obtain the Memorial Crystal: Apito and see whether it bears on the murder — and repeats that Carl must still speak to the high cleric in Club Vanquisher (B5 ch. 77). The masquerade and the murdered son are one storyline now.

'We have no clues as to who killed Geyrun other than the dog […] his time in the Nothing has made his memory unreliable' (B6 ch. 18). Amayon, one of the four princes of Sheol, 'may have some insight'; he laughs, says he was witness to the deal being signed, and names three brothers as the price (B6 ch. 58, B6 ch. 69).

Amayon's price (B7 ch. 2); Hellik's denial (B7 ch. 54); the confession (B7 ch. 83); the hoodie (B7 ch. 86).

Carl's summary of the case: Samantha was there when someone was hired, 'her memory is a little spotty', and 'One of them, Amayon, claims to know who did it' (B8 ch. 70). In the arena: 'Emberus, I know who killed your son' (B8 ch. 94); 'The first person to kill your son was the god Khepri' (B8 ch. 95); and Carl's own conclusion that 'one of the key details of the whole mystery was a lie' (B8 ch. 95).
