Eden Group : it's a group created to help players to gain experience quicker within the game. It propose different quests, depending on your level, and you can take them as much as you want (and believe me, this thing is usefull when you're in a high level and only gain 0,1% of experience per monster haha xD). With the Eden group you can also have equipments.

To enter the eden group headquarter, you need to talk to this npc:

Quick view of the headquarter :

Mt Moljir : it's a big moutain within the game, situated between Prontera and Aldebaran. It cover several map in the game and you can find different monster on it, there is also Mjolnir Dead Pit, a good leveling spot tbh.

Savage, Baby Savage : just some monster you can find. With a special you can even tame the baby savage. Here a visual of them :

Tower of Geffen : I'm not exaggerating when I described it as a huge thing, here is a visual  °°

So, this tower got 2 function in the game, the headquarter of the wizard guild and an underground dunjeon were you can go to gain experience (but there are some ugly monster with the ghost type there, and you'll need elemantary weapon if you want to fight them..)

Warlock : Yeah, new character here ! Whessung as a Warlock, same, don't ask me why but he was the first to appear in my head when I was thinking about someone for Hwasa's mentor.

Warlocks are the last « evolution » of the wizard class, and here is an example on how awesome their skills are.

Rune Knight : They are the last evolution of the knight class.

Instructor Boya : it's a npc of the Eden Group (dunno why I wrote about him being an old student of Solar father tho, it just came like that while writing that part xD)

Poison Spore : an aggressive version of the spore. Not really difficult to beat it if you have the right level, but be careful when you do mob training tho (mob training : killing a lot of monster at the same time)
