Cassandra can see nobody else up on the rooftops other than, of course, Amira who is well-concealed from the crowds below.
The light from a couple of the lanterns held by the group below starts to play along the rooftop, catching the conjurer in a beam of light.
"That's not Blackjack."
"Who is it, then?"
"Wha'd she do with Blackjack?"
Tobias then speaks up. "If you're all finished with this Blackjack nonsense, can we get started? He ain't doing anything about the rats just like he ain't doing anything about the woman that murdered the king."
"'Cept rescuing her." mutters Jeremy.
"We ain't getting into that now. We're here to kill rats. This ain't about politics."
"You brought it up..."
"Shut up, Jeremy. Now let's move out!"
Finally, the group stops blathering about Blackjack and moves north along the docks. A short while later and the group overlooks a shallow channel with a grate heading into the sewers and catacombs beneath the city. The grate is closed, but the strong laborer muscles of a couple of the dockworkers make short work of that with the grate scraping noisily along the stonework.
"OK, we're in first. Groups split off at the first junction. Leftward as usual." Tobias calls out as he drops into the channel and then into the tunnel.
