BONNIE

N doppelganger disguised as female Tethyrian human barmaid

"Bonnie" works at the THE YAWNING PORTAL in WATERDEEP as a barmaid. Unbeknown to anyone (except MATTRIM "THREESTRINGS" MEREG) she is, in fact, the leader of a doppelganger gang who arrived in Waterdeep about a year ago.
She works as a barmaid to help the gang make ends meet and does a fine job of impersonating a friendly, talkative barmaid but her true intentions are harder to fathom.

"Many adventurers pass through the Yawning Portal on their way to greatness. All of them try the ale"
