Okay, so
Unless the poison was found and placed in CH2, we should be able to solve from this?
Anyone who was in the Tower from the start is clear.
I know kat was there from the start because of “detestable slithering movement”.
eevee only briefly left to get a golden bar, but I think they were there from the start.
Pretty sure Apprentice was there from the start as well, I remember them making some Gilded Drake joke.
I remember Marl singing a song for the dragon at the start, and I’m pretty sure Arctic was there from the start as well.
But more importantly, Night only left the Town Square at 2021-02-16T19:37:00Z, so that means only Tangeld had the opportunity to place the poison before Trochi went into the Tower.
