That’s a bit spooky - I was about to mention Dungeons and Dragons as I remembered hearing the theme tune meant I had to go off for piano lessons.
I’d agree with that too. I think they got over leaving the unicorn behind after the first time (that was just a handy device for the writer as there was nothing else to stop them) but surely, after the Venger business, they’d ask Dungeon Master if the portal was Venger-proof. If not, they’d just say…nah, no thanks. Help those poor tribal people yourself old man.
