Little bit of an update; at the risk of sounding like I'm bragging - I'm not, just really, REALLY happy - I managed to reach level 80 just under an hour ago! Was able to go to Endwalker and do the first Quest for that Beast Tribe I mentioned; have to say, really looking forward to what the rest of the story for it is going to be like!

Thank you, guys, so much for all of your help; I really don't think I could have made it here, this quickly at least, without your help!
