Acheron Quests
Advertisement:
Acheron, a mysterious island near the continent of Mu, has become riddled with strange elemental monsters. Deruvish, who is camping in Acheron, is researching the strange island with Vanert members in search of Secromicon Fragments. However, the elemental monsters were far too strong for them to handle, forcing his party to flee. Deruvish decided to stay behind, however, and continue the research on the strange island. He understands the basics of these strange elemental monsters that roam the island and is willing to teach them to anyone who can help him. By completing some of his requests, he will help guide you to conquering this island!

Game lore...

Deruvish says,

"No, no way! How... How did you get here? First, take cover here. I don't know how you got to Acheron, but scary monsters come out here that you cannot see anywhere else. Oh! I forgot to introduce myself, I'm Deruvish. I came after Vanert in search of Secromicon Fragment. I'm the only one left now. As soon as we got to the island, we were attacked by element monsters. We lost a lot of adventurers from that. Even the survivors left the island with Vanert. I was left behind with a few others to save the other members."

The Only Survivor of the Adventurers

Deruvish says, "From what I have found out, I think this island was a peaceful place with spirits. Something must have happened to transform the spirits to monsters. However, when they transformed into monsters, they still had the abilities from when they were spirits. They are still dangerous. I don't know why they have transformed into monsters. However, when you see monsters here, you must have an elemental item called Pentagram to fight them. If you want to continue adventuring, you can get Muren's Book of Magic pentagram item. Please hunt down monsters in Atlans or Acheron's Alkmar area to find Muren's Book of Magic."
