Alistair

Alistair is a member of the Comrades the party of the Tomb of Annihilation campaign, being introduced at the door step of Syndra Silvane's house. She was played by Weeb.
She is a tiefling rogue and is known for carrying an absurd amount of daggers and aggressively uses them whenever she is able to. She is also the carer of the gnome Zook, looking after him and making sure he doesn't go completely skits. 
After the final session, with Zook becoming the supreme leader of 'Port Nyanzaru Two: Electric Zookaloo', she became the political adviser of Czar Zook during his rule of the new communist regime, plus the fact she herself was already a determined communist, thus making herself commander of the KGB.
