Liam is back for one more bonus episode! This week he chats with historian Donal Fallon about the fact and the fiction surrounding Vikings.

Step back inside the Seer's visions with episodes 3 through 6 of Prophecies of the Seer. You'll hear the Seer foretell of Floki's adventures across the sea, Ivar's machinations, Bjorn's new enemies, and a brewing civil war. Make sure to put on headphones for the full 3D audio impact. Find all the episodes on Apple Podcasts and at History.com/TheSeer.

In our final episode before the Season 5 premiere, Liam sits down with Ivar (Alex Høgh Andersen) and Bjorn (Alexander Ludwig). He keeps them separated though, as it seems the sons of Ragnar aren't getting along right now. Plus, Michael Hirst gets us amped for what he calls "the best season yet."

The magic of Vikings is in making what you see on the screen seem like it could have taken place in the Viking age, more than a thousand years ago. So, the places where scenes are shot, how those locations are decorated, and what it all ultimately sounds like become incredibly important. This week, Liam gets into it with three of the people responsible for making modern locations look at sound Viking authentic: Set Decorator, Jil Turner, Locations Manager, Manus Hingerty, and Emmy-nominated ADR Editor, Dale Sheldrake.

Over its four seasons so far, Vikings has received critical and fan attention not just for the storytelling and performances, but also for the unique, groundbreaking look of the Vikings world and the characters in it. This week, Liam hears from some of the most influential people on that look, Emmy-nominated makeup and prosthetics artist, Tom McInerney, Emmy-nominated hair stylist, Dee Corcoran, and stunt coordinator, Richard Ryan.

Katheryn Winnick has gone from playing a simple Shield Maiden, to playing one of the most powerful characters on TV. But her ascent didn't happen by accident. She's been fighting her whole life to get to where she is - a fight she happens to be well equipped for thanks to holding a third-degree black belt in Taekwondo. This week, Liam hits Katheryn with the tough questions, and prays that she doesn't hit back. Also, Liam hears from Cavan Scott, writer of the Vikings comic books.

Vikings is a show that famously will kill off just about any character. But whose job is it to tell the actors that their time has come? That would be Producer Keith Thompson, or as the cast as dubbed him, "The Angel of Death." Liam speaks with Keith about being the bearer of bad news, actor George Blagden who has first-hand experience on the matter, and actor Alex Høgh Andersen, who may or may not be hiding in a closet. Also, Vikings armorer John McKenna shows Liam his wares.

What's it like to jump aboard a successful show like Vikings while it's already on the move? To find out, Liam travels to the Wicklow Mountains and catches up with actress Georgia Hirst, who started on the show in season 2, and Adam Copeland (formerly WWE's 'Edge'), who is joining Vikings for Season 5. Plus, Einar Selvik, whose band 'Wardruna' has composed music for Vikings, talks about creating the sound of a culture no one has ever heard.

Liam hears from creator Michael Hirst, Producer Morgan O'Sullivan, and Director Johan Renck, who directed the first three episodes of the series. Together, they set the tone for how the world of Vikings would look, sound, and feel, right from the very beginning. Everything from the way characters speak to the bushiness of their eyebrows painted a picture that would endure throughout the series. Also, Liam steps into the world of Production Artist, Dave Wilson, whose work creates the visual look that eventually ends up on screen.
