Hello! I use to RP a ton back in MOP-WOD and I’m ready to get back into it with my Gnome Mage! I just don’t know where to begin with her, idk anything about mages in lore nor very much about Gnomes.
What’s the best source for accurate material on my class/race?
Is TRP3 everyone’s go-to now or is MRP still the main one?
Thanks again!
(My first RP character Cannibal helped me figure them out and use to answer all my Lore junk questions when I was new!).
Wowpedia is typically the best and most up-to-date source for everything lore. Try these:
https://wowpedia.fandom.com/wiki/Gnome
https://wowpedia.fandom.com/wiki/Mage
You could also search for gnome and mage RP guides in Google and YouTube. TRP is the main RP profile add-on now. 
The game itself… go back to the starting area and interact with all of the various Gnome NPCs.
Thank you so much! 
Sorry been ages since I developed an RP profile and had Cannibal as bnet bud to ask my questions haha.
You’re welcome, no worries! I have a gnome RP character and also wrote an RP guide so if you have any more questions, don’t hesitate to ask!
