Not too spoilery. It's mostly talking about parts in worlds.

If in the End realm some see an animal or creature and they'll place them back into a more fitting world. If they find an animal or creature which is special or unknown, they'll take it for research. If it's a human, they'll take it to the Queen and let them decide what to do with it. This explains the red butterfly and the pink rabbit, they aren't known of.

In some allyways are seen people in white cloaks but run off if someone gets too close.

In the seas, pirates will be seen sailing. On beaches are some beached ships with treasure.

A bard with a flute. The flute shows the hologram of a music sheet when played. A bard who follows the Illusionist was gifted his flute, now he sings in an inn surrounded by beautiful women. 

Turtle... Must have turtles somewhere.

Each kingdom has a flag. The End kingdom's flag is a black and purple dragon.

A cave system with a much larger than average amount of gems and riches. Emeralds, Diamonds, gold, iron. Whoever found it would be rich.

There are other kingdoms in other worlds. One is where a King wishes to give up the throne but has no heir to the throne, so is searching for a Queen.

Whoever tries to leave the cult of the Illusionist will be tortured and brainwashed into staying.

A shop which sells horse gear and horse shoes. Even horse armor.

A white drink called "The Banshee." It's white with a swirly pattern which has berries in the ingredient. It tastes sweet but also minty.

A bar named "The Sun And The Moon". It's a reference to the sun and moon goddess. Luna, the Moon goddess and Malinda, the Sun goddess.

Crabs in the candy dimension are made of red jelly and their organs taste of strawberry flavored lollipops. (Now I wanna eat it)

(Kind of spoilery with someone's return)

When a certain type of individuals return, there will be a celebration to make flags of those people to celebrate their arrival.
