So… how do I start?

Now that your guy's in the Characters tab, we can talk about an entry point. I usually do it in PMs, but since we've got several prospective joiners, I can give you the low-down right here:

In our in-game 'yesterday', everyone had a pretty busy day. In the early hours of the morning Blue Team took out the Orphan of Kos, escaped back to Limsa Lominscuttle Town, and essentially took the rest of the day off in a nice beach episode. Meanwhile Yellow Team spent the afternoon climbing Split Mountain, flying back down, and fighting the Red Eye boss. As 'today' begins, most of Blue Team is meeting inside Alcamoth, the floating futuristic citadel that's the home base for the campaign to defeat Galeem. Yellow Team ended up spending the night in (or just outside) Gerudo Town in the Sandswept Sky. We've also got White Team currently embroiled in events on Dragonspine in the Frozen Highlands, but I wouldn't say that's a valid entry point right now. So the choices are:
[list][*]Bede has been in a town or other settlement near Alcamoth, and met one of the mercenary teams exploring the world. Maybe he was looking for a way out, but those under Galeem's Influence tend to stagnate. He might have been curious and questioned the mercenaries, or requested their help, but the end result would be that he became interested in joining them and ended up back in Alcamoth, where he would be freed of Galeem's influence and then able to join Blue Team as they have a morning meeting in Mercenary HQ
[*]Bede happened to be in the Sandswept Sky, and is either staying in Kara Kara Bazaar at the oasis outside Gerudo Town, or ended up there just this morning. From that point he'd probably take note of Yellow Team, and maybe eavesdrop on their conversation in the saloon, thereby learning of the train station in Gerudo Town that could take him anywhere in the World of Light, prompting him to tag along
[*]Bede could be inside Nyakuza Metro, the giant indoor station that serves as the hub for the aforementioned trains, and Yellow Team will meet him when they arrive.[/list]

Personally, I think either of the latter two options would be a bit cleaner-cut, and if you picked the last one you wouldn't even need to think up a reason for him to be in the desert. Lots of people use the metro to get places, after all.
