Hmm, it appears to be a traditional gnoll necklace.
Wait... This glowing red mark...
A Fomorian emblem? That's what Marrec said, too?
Long ago, the gnolls worked closely with the Fomors, but something happened and they split ways.
Gnolls today are peaceful and tend to keep to themselves. We haven't had to worry about them.
They created necklaces like this, back when they were part of the Fomors, but purged them when they left.
There are two possibilities. First, this may be a remnant that was missed during that purge. Unlikely, but possible.
Second, this may be something they've created recently, which means... something very, very bad.
Could they have rejoined the Fomors? I can't say for sure, but with the gnoll attack on the bell tower...
Well, something is definitely brewing over at the Ruins.
