# Our Collections

## Worlds Within

The first drop of the Worlds Within NFT started in November and ended on January 16th. This drop consisted of VR-ready worlds which users could Explorer in any commercial VR headset on the day of the mint! Every world can also be viewed on Desktop and Mobile in the NFT itself.

## Nebula Serum

On February 22nd, we airdropped 13,000 Nebula Serum for users to burn. Our goal as a team is to create utility that would cause the holders of the nebula serum to burn it. The first implementation of this is our release of The Explorers.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.worldswithin.io/overview/our-collections.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
