Good evening!
First of all Welcome!
There are 2 Servers F2P and P2P and 2 Factions. League side and Empire side. During Leveling you might not see too many players but in the capital (Novograd for League side and Nezebgrad for Empire side) you could ask in /Zone for an exp / lvling guild which will give you +20% more Exp. Also some chats (Which is always nice to have

) if they´re active enough. Also you can make someone a "best friend" this person will be able to run raids with you and also can share a mount with you. Also you will get a Mentor who can answer you questions and there´s a quest for it in the capitals which gives you some gear and gold if you do it with your mentor.
If you have any other questions feel free to ask about it either here or on the Allods Discord Server too!
Have fun and I hope you´ll enjoy playing Allods!
Greetings
