Argint notes no one that sticks out. A head investigator shouts orders, mostly pertaining to the cleanup of the rubble on the street. A blue-skinned tiefling- that appears to be an engineer, is scanning an oversized blueprint of the Tower, and quietly appraising the damage.
No one save the elf healer seems to be of any special note. The general sounds are a hushed, subdued drone of murmurs, with the head-investigator's high screeches occasionally breaking the monotone.
Argint scans the crowd of onlookers and investigators for anyone out of sorts, seemingly privy to information, or appears to know what they are doing.
