Hey, welcome to TalonRO!
What class did you start with? TalonRO has its own Wiki with lots of guides and helpful stuff for new players. https://wiki.talonro.com/Main_Page
Learn about the Eden Group quests (helpful for new players!) and the Rental Item system. And don't forget to vote every day for Copper Coins, which can be exchanged in-game for Talon Coins at Reward Guru in Prontera! Talon Coins are a special currency in TalonRO which can be used to buy a lot of different and powerful equipment, or sold to other players for a lot of zeny.
