Mafia 95. The Wardens' campaign against Urubaen.

City-based Hive units don't generate clues upon killing.

Ah, that's what it is! I didn't think of that. Then the blue scales are just a hint at Sapphire's role, most likely. I'll update my version of what happened:

City:
Eragon - joint attack on Arandor with Sapphire.
Sapphire - joint attack on Arandor with Eragon.
Arya - blocked me, thanks.
Solembum - unrecorded Night Duel.
Nasuada - unrecorded Night Duel (possibly found Elva, see last paragraph)
Angela - Arandor, killed.
Roran - unrecorded Night Duel.
Oromis - blocked Tenshi.
Glaedr - covered Sezam, successfully! Lost natural defense.
Elva - unrecorded Night Duel (possibly found Nasuada, see last paragraph).

Manic:
Blocked Heroist ("Suddenly, a terrible, heart-wrenching scream echoed behind him. Heroist was stunned and paralyzed with fear.")
And probably changed his status.

Mafia:
1) Thorn, indiscriminate fire attack on Sezam, but he was covered by Glaedr. The latter lost his natural defense.
2) and 3) - unrecorded Night Duels.

Now it all looks a little more logical.
