Hey there Miroell and welcome to the RPC! We have a lore thread here that goes over several lore type topics of the world Hydaelyn. There is also the lore thread on the official 14 forums that has topics that even goes into racial names brought to us by the head people at SE who created the lore themselves!
There are also a few wikis out there that get into racial information, naming conventions for each of those races, and other bits of information.
As for what server you should go onto....
I would suggest checking out the Linkshell > Other section, as there has been a few of us smaller servers cropping up trying to step up to become Roleplay locations.
By consensus of the masses, most here on the RPC haven chosen Mateus, but that is not the only option! I would, again, check out the Linkshell > Other, see what is there, and look maybe also at the Making Connections thread.
Where you go from here is up to you, but if you do decide to go with Mateus, please feel free to PM and I will get you hooked up with not only the Mateus HUB Discord, but also with the Roleplay Mateus Linkshell (and Discord).
Best of luck!
So, I made a character on Mateus, because it was the first reply and I just wanted to play the game. And I made a Ranger! Highlander person! Mostly because I kind of 'have a name' and apparently the name fitted perfectly with them. And I got into the discord and the Linkshell whateverthatthingisbecauseIhavenoclue. So, I'm getting on my way to exploring and adventure!
Also, I was half-panicking, so both are right but wrong. Yay. Thanks for soothing, I needs.
