The story of Trove revolves around the storyline of the real-life comic strip, Hell's Kitchen. In this world, there exists a restaurant called "The Larder". There, you will find a group of humans working as waiters, delivering food to the various clients of "The Larder". But, instead of eating, they're having a contest to see who can kill the fastest zombie. The gameplay of Trove is influenced by the same cartoon style that's used in Hell's Kitchen, with the use of a lot of the same greens for combat, and the same browns for items and clothing that give the restaurant a homely feel.
Trove's endgame involves going to the Plane of Telara, where you'll find that the Golden City has been destroyed. From there, you'll have to earn your way into the higher levels of the realm, called "the Planes". You'll also need to complete quests and go through the daily activities associated with the realm, which can be very challenging, as most of them involve doing something like killing a lot of zombies or creatures to earn experience points that can later be spent on items and abilities that will help you progress through the Planes. The final goal of the game is to reach the highest rank possible - which involves a lot of grinding, as you'll learn when you get close to the goal. But, if you're into the daily challenges, you'll quickly realize that Trove isn't just another hack and slash MMORPG; it's an effective means of advancing through the Planes of Telara while staying in character.
