Chalkos's Links
Chalkos views Minthe as a pain in his rear as well as a consistent source of trouble...but years of working together have forged a friendship, of sorts, a fondness beneath all the vitriol and shenanigans that the two get upto.
Naturally, this won't stop him from attempting to usurp their plans or cause them trouble in defiance to their very nature, but it is enough that Chalkos will sit beside Minthe and ask them what they happen to be upto.
