Bestan ir'Tonn is an agent of the Dreaming Dark. Fifteen years ago, the Inspired dominator Tirashana infected Bestan with a mind seed. Today he is one of three Inspired moles in Sharn. While appearing to promote the agendas of his supporters, he has actually been stirring up dissent and discord across the Council. This is one of the most consequential hidden threats in Sharn's government — player characters should encounter Bestan as a long-serving, well-connected Boromar ally before discovering that his true loyalties serve an entirely alien agenda.

Kilk is a Tyrant fiction. The councilor for Lower Tavick's Landing is not a person but an identity created and maintained by the Tyrants, played by various changelings at different times — sometimes even by Ek, Tyrant One himself. Through Kilk, the Tyrants have a way to affect the city through a respectable facade, dealing with groups like the King's Citadel as a legitimate councilor would. This information is from the Tyrants article's DM Secrets and should be deployed consistently.

Hruit is a giant owl who can assume human form. The Rising from the Last War sourcebook identifies Hruit as a giant owl rather than a human druid. This detail — that one of Sharn's councilors is literally an animal who shapeshifts into human form — is a wonderful revelation that should emerge through play rather than exposition.

The Sensos family's fear of displacement. The detail that Sorik Sensos's family fears displacement from the Sharn Sixty to make room for Tomollan adds personal stakes to the rivalry beyond ideology. This is internal family politics that player characters would need to investigate to discover.
