The fun part of PbP is that you can use the time machine if the DM moves you past where you want to be. Such as now, I'm going to assume that you all go to the secret door. But if you want to attempt a different entrance then let me know - I will unwave the DM hand.
You stand before the secret entrance at the back of the temple. This entrance was described clearly to you all before you left on your mission by an escaped slave and you have had no trouble finding it. The slave was so traumatized that he remembered climbing up a ladder to a hallway, with others, and escaping through this secret door that another slave knew about, or divined in some way. By the time the slave got back to civilization he was the only one of his group left, he was in such a fog that he's uncertain if they were killed, or went their separate ways, or what may have happened. It is nighttime and occasionally the shadows of guards pass overhead, but none of the guards seem to notice you at all. Blodgett quickly finds the secret door, even in the dark, and before he can even check for traps the secret door has opened easily and the party sees a 5’ wide hallway before them.
Always double check the totals below that they are up to date. This is one of the most important pieces of my DM tracking mechanisms, and I assume it's good, unless someone can prove otherwise.
