Hello! I've compiled a couple of resources for xena related things here.
My first recommendation is a website thats been around since the 2000s and is loaded with the old internet charm and a great archive resource for everything related to xena, They have a great episode guide that gives brief descriptions of the episode if you're interested in that! Its good to reference while using a watach guide to see if its worth a watch or not!

Another classic internet Xena site is Whoosh! They've been around since 1996 and are get for finding anything archived such as interviews, articles, or anything else.

If you're looking for videos i suggest checking out either Xena News or to look at the Official Xena Youtube for clips, bloopers, and etc.

Finally, there are multiple behind the scenes movies made by the Official Xena Fan Club about specific episodes in season 6 that are good to watch! They have a long documentary about the making of season 6 episode 4 'Who's Gurkhan?' that can be watched in parts!

Here's one for the final episode of Xena: Warrior Princess, season 6 episodes 21 and 22 'A Friend in Need' that can also be watched in parts!
