If you’re curious about Warcraft lore, they recently started doing the Warcraft Chronicle series (currently there are 3 volumes) that basically summarize and tidy up much of the lore. (What I mean by tidying up is that the lore has gone through some changes over the years as they have added new details, and now wish to tie some things in together that were added much later so that it all fits together a bit better.) They are very helpful with catching one up to speed on Azeroth’s history fairly quickly, and might also give you an idea of what aspects of the lore interest you the most! I also recommend Nobbel87’s videos on YouTube.
What’s also nice about roleplay is that it’s an opportunity to learn lore by having your character ask in-character any questions you might have out of character. Stormwind University, for instance, hosts neutral (meaning both factions can attend - just come with a few Elixir of Tongues potions from the vendor in Dalaran Sewers in Legion, so that you can understand everybody!) lecture events that can teach people bits of lore, and you can ask the staff questions after they’re done teaching.
It’s a very fun way of learning the lore as you go via roleplay, and if you make any mistakes about the lore, it can always be explained by your character just having a misunderstanding or remembering something incorrectly. Plenty of people in real life don’t know things that should be common knowledge, or at the very least misunderstand the details. It’s completely realistic to imagine this is equally common for roleplay characters. Nobody’s perfect, after all!
Don’t worry if you don’t have the details totally sorted out before engaging in roleplay. Honestly, it can be a good thing to go in with only a loose idea of who your character is, and to learn about them as you interact with others. After all, you might run into a group or guild you really, really like and have a great interest in having your character join them because they have a cool idea for a community, but if who your character is has already been rigidly planned out ahead of time and winds up being a difficult match, you might end up dealing with the headache of trying to justify how you’d go about getting them in there.
I’ve run into that problem in the past, and it’s since made me learn to not over-plan characters too much and just see what happens naturally. You can always add in extra neat details about your character’s past as you go along and get inspiration for what “fits” the character they are becoming, and say that it is a detail about them that either hadn’t come up until the right time in roleplay or was a detail that they never shared with anyone they’ve encountered before for one reason or another. Maybe they needed to earn that person’s trust first, maybe they were nervous about what others might think, etc. Even the backstory doesn’t have to be fully fleshed out ahead of time, really!
I like your starting backstory idea so far! It’s definitely something you can continue to shape as you go along! There are also plenty of Pandaren and monk roleplayers around that you can have your character learn from and hang out with as he continues to learn about Pandaren culture and the ways of the monk.
Most importantly, don’t be afraid to put yourself out there and approach as many people as you can ICly! A good way of meeting people’s characters is to check out the many events posted on the forums, if you can attend them. I’ve had very good experiences, and people are generally very patient and more than willing to help a learner. Your character and their story will grow naturally as you meet people who shape their life, but the first step is to take the chance of saying hello and seeing what happens from there!
Also, welcome to the community! I hope to see you around in the future!
Edit: And on an OOC note in regards to roleplay advice: I think to some extent, we all worry more than we need to about potential rejection or “messing up”. I haven’t met many roleplayers, myself included, who don’t put a lot of pressure on themselves to make a great impression. We’re all a little bit paranoid of that one awkward/negative experience out of dozens of positive ones, and many people unfortunately will make themselves so afraid of rejection that they ultimately stop roleplaying much at all anymore. Nothing makes me sadder than when people isolate themselves like that. It always happens with the kindest people, too.
Like everything else, roleplay just takes practice to get better at and everyone makes mistakes, but most mistakes aren’t as bad or unforgivable as we sometimes tell ourselves that they are. You’ll always find folks out there who enjoy your company, and they would be missing out if they never got to meet you!
