New client: Kayne (last name unknown)
Half-giant living in local inn. 70+ years old. Staunch ally. Likes a direct approach. Protector of small and not-so-small furry animals.
Fee: pro bono
Item of interest: 1 axe (silver, double-bladed, big)
Last seen: 32 years ago, impounded by Gold Clutch guards during arrest
Current plan of attack:
Interview current Gold Clutch guard roster, perhaps some guards are still around. Kayne is very very memorable, so chance is high that they may remember him.
Check depot records. Precious weapons might have been resold, there might be logs available.
Put out feelers at pawn shops in Gold Clutch and the Racks.
Inquire at local bars and fighting pits if anyone is using a weapon matching the description. 32 years is a long time and it may have been passed down a few times. Unlikely that it is being used by guards or soldiers as it is non-standard. Likely needs to be wielded by a Giant/Half-Giant. Its double-bladed nature leans more towards gladiatorial or brutal combat, thus fighting pits or gang members.
Divination spells could help, if funds would be available.
