'The only thing that I don't understand is how they smuggled the weapons in and out of the office. Dimensional amulets don't work in the City Hall and most of the artifacts are as big as my arm.'
The answer came when the body of the woman split in two like a watermelon, revealing a short staff in place of her spine, an amulet where her heart was supposed to be, and a chainmail floating in the middle of her chest.
The creature had no internal organs or bones. Under the skin, there was what looked like a bright blue gooey substance where the missing artifact had been stored. The gelatinous substance was dense enough to keep everything in place without making the chainmail clink.
The Doppelganger didn't show any sign of discomfort as it took the artifacts out of its body and cleaned them from the residual goo with darkness magic.
