To bring some light into the topic:
Using a gm character you can do /transport_node <Node-ID> to get to any map you want.
To get into Helonia Coast, you would use
If you want to remove the quest requirements completly you have to edit the S_Node.ini and the C_Node.ini.

Code:
3|日輪海岸|0|無視時間與氣候,永不停歇的貿易帶來白金海岸的美譽,卻也帶來了貪婪海盜的覬覦。|F0012|F0006||8|100|2|S003||S003M|S003S|bgm003|bgm003|sound002|sound002|1|1|||489;139|日輪鎮|249;386|貝拉果園|550;487|風車小屋|661;298|白金海岸|446;404|風車草坪|140;576|翠林山|642;629|貓眼海盜據點|341;338|漩渦深淵|||||||800|||||Loading_003|1026||||||0|
This line is for the map 3 (Helonia Coast), nearly at the end of the code you can see a "1026". Its the id of the quest that you have to complete before you are able to visit the map. By removing this number you also remove the quest requirement for the map.

Code:

This means that every character that is lvl 8 or higher can enter Helonia Coast. To remove all quest requirements you have to do this for all worldmaps.
