19:14 And it's all about going into the oldest tower. Now I won't go into the the details of the story. But, I mean, he's he's quite open in that. Yeah. This this is a this is a pretty standard, if I have the right word.
19:28 It's all all kind of like, what you would expect from the genre kind of dungeon delve. And it's going into the tower and working out what's going on and dealing with the bad guys. And there's a couple of lovely little other storages of subplots that that work through it as well, which are really quite nice, which can lead on to further adventures afterwards. So it's good. I mean, there's a lot to it.
20:26 It's looks lovely. I mean, it's like I haven't read it in detail, but I did particularly pick out a couple of the, kind of, nice little story lines that run through it that you could that the players can pick up upon as they as they travel through the old this oldest tower. And then that leads on to stuff that you can take into further adventures. So, yeah, it's a lovely little bit of work. Very good.
