Barrel was a Lamia, not a Mon Calamari (I use Barrel the Lamia NPC the same way Kenny is used in South Park). Also, your turn to post, since Rotramel wouldn't have much to say/do upon meeting Ageron and Aleya.
Yeah. Regardless if he had a mostly isolated life, he'd at least hear about the Bogan and Jedi. Also, since he's been traveling, he'd most likely hear stories about the Jeid and Bogan really quickly.
I'll wait until tomorrow to see if anyone else joins before posting again. If you want, you're free to sneak into the secret laboratory and stumble into Rotramel
