Just in case people here don't know about this yet, players with validated accounts now can "recruit" their friends into Faeria with rewards for both. The details are at https://www.faeria.com/recruit-your-friends
The short of it is that if you recommend recommend to your friends through their email form and then your friend uses that email for their Faeria account validation (And they indicate you as their recruiter after completing the tutorial) you'll both get some rewards as your friends level up.
There's also some exclusive rewards for having multiple friends reaching high levels. Look at the link for the details.
