аа, там есть и продолжение!

Chris rolled, a mere 8 on the die, but the DM didn't care. The cultist cracked under the pressure, he wasn't used to being treated like this by Paladins, especially this one - since his cult has dealings with him before. Something about him had clearly changed.
He gave us the information about the 4 other locations, and said they all made a rough pentagram, with the Palace spire being the vocal point.
The wizard worked out that if they needed to make such a shape, then the ritual was dependent on such geometry, but if could take out one section and it still worked, the focal point must be the palace spire.
My character, the a former knight Captain of the now Tyrant king (I had a few levels of Paladin in there too, but had been shamed out of mentioning them us far), knew the Palace lay out well enough to draw a detail map, detail enough for a teleport.
True to his word, Sir Peter helped the cultist up, use his lay-on-hands to fix him up, but told him that he had to lock him in a holding cell until this was all over. He said sorry, but it was necessary if we were to retain surprise.
We made our plans, and teleported in to my Knights old barrack rooms. The men stood to attention, still evidentially loyal to me, and in the presence of the rightful king.
We got the details of what had been happening inside, turns out they were actually trapped in the room by some sort of ward on the other side.
Clearly things were going down. However, we ended the session there.
