Situated between Vern and Rohendel, you will find Hope Island on the Lost Ark Gold West side of the world in Lost Ark. Here, you have a chance to gain one of the many Island Tokens in the game. Luckily, finding this token will also raise your XP quite a lot as there are a few steps you must take first.
However, you, unfortunately, won't be able to access Hope Island right away. You will have to do a few short quests on Goblin Island in order to even unlock Hope Island and get the token. Once those quests are completed though, you will be one step closer to being one token richer.
You must first go to The Goblin Island and speak with Gobius XXIV to accept a quest. The two quests you must complete to unlock The Hope Island are A King Who Is Not a King as well as A New Sea and A New Land. However, in order to do these quests, you must first unlock Gobius XXIV as an NPC through the Wall of Procyon quest. You must then build rapport with him by playing music, completing small quests, et cetera.
To unlock Gobius XXIV, you must complete the quest called Wall of Procyon. In North Vern, you will head to Vern Castle; specifically the Queen's Castle. You will speak with Ealyn. She will want you to come back with a strong ship after she gives you all the materials she has. Once that is completed, you speak with her and complete the quest.
To complete this quest, you must speak with Dadilloo. Once you do, you need to talk with Sezo, Neth, Chole, and Nanette. Following the map, you will start on the far left side next to the red heart. You will head up from there, around the curve then come to that Y. Two of the people you must talk to are on the upper path and two are along the lower path.
If you go along the lower path first, you will follow the path, cross a bridge then find Dadilloo in some long grass after you cross the bridge to the left. Once you speak to Dadilloo, head through the fence to your right. You can choose to fight the mobs you come across or just run past them. However, they may become annoying when you're speaking. You will need to buy Lost Ark Gold walk around the other side of the fence, and you will find Nanette next to this small hut.
