With no other better plan, the League of Heroes had to hold up in the League of Heroes Castle in Knighton to regroup their forces and come up with a decent plan. However, they were doing poorly, no one could focus because in Ninjago, the Undead Army was taking its power on the sea and had begun to approach land.

Fortunately, they could count on support from the Ninjago navy and army. Thanks to the great leadership of strong soldiers Jake Sully and Miles Quarich, the army cope and held off the invaders's attacks until the heroes of the land return to war with their allies.

Aspheera, Pythor and (Y/N) searched every nook and cranny of the library, but to no avail. Nothing, no mention of travel to other worlds and not a single word even about the existence of other worlds. Wanda and Misako decided to join them as well.

- There is nothing. No scroll, book or paper about other dimensions.... - (Y/N) sighed gloomily as she closed what must have been the fiftieth book and placed it on the big tower of books. - LIBRARY AND I LOVED YOU SO MUCH!!!

She roared out of pure frustration, throwing her hands into space and banged her head against the desk, burying her face in her arms. Pythor approached his friend and awkwardly patted her on the head. - Oy, (Y/N). We have to keep looking, you'll see, soon something will be found.

- What....? I think there is something. - said Wanda, approaching the table where they were. (Y/N) lifted her head slightly from her arms and looked indifferently at her mother, who put the book in front of her. - Look.... We already have tea, and here is a mention of one artifact that will help "navigate" us in other worlds.

(Y/N) raised herself fully and looked at the book. Misako and Aspheera joined them and glanced at the book. - The Traveller's Map?

- Read it well! - Wanda rebuked and lightly slapped her daughter on the head. (Y/N) squirmed slightly and sighed, looking into the text of the book. - Here is a special command for the Map. The holder of the Map can command it to give him directions to a given location at a given time and place. It is up to the will of the holder where to point the direction. When the user finishes using the map, the entire will change into blank paper, until the holder's next command.

- Sounds like those treasure maps. I don't know why, but I feel a reference to Pirates of the Caribbean or some other pirate movie here. - Pythor noted.

- You're not wrong. I wonder if, if you commanded the map to show the way to Eldorado, would it work. - Aspheera said. - It would be nice to find a city of gold.

- Well... But where can we find this map? - Misako asked.

- The Traveler's Map is a great artifact, but where it comes from.... From Knighton or Ninjago? - Pythor asked further.

(Y/N) flipped a few pages of the book. - The Traveler's Map was lost without a trace during battles with sea monsters. Legends say it can be found somewhere near sunken ships in the sea.

- The sea monsters have long since been gone beneath the waters. But it is not out of the question that they're still alive. - Wanda noted.

(Y/N) flicked her tongue and looked at her friends. - Well.... Get your swiming suits on. We're going to swim!
