The Legacy Heaven is an independent and decentralized combination of Selforge City and the Inner Planes, with smaller communities scattered over wide evolving territories.

It was created in answer to Lawrence's ubiquitous womanizing and extreme fertility, as the countless children endlessly conceived couldn't join Selforge City without compromising its social stability, and even those made with individual citizens would be too much for them to handle due to their high-paced increasing numbers (although their mutual daily access to the Metaradise allows them to freely meet and catch up as they see fit, as mentioned in the last paragraph of the titular section).

Aside from the transitional bubble-worlds they individually grow up into, which have finite dimensions and a tutorial purpose, the Legacy Heaven is functionally infinite as it expands and evolves alongside Lawrence's chidren, and since there is no end to it or what it has to offer, there is no desire to go beyond it, nor the idea that such a beyond even exists in the first place.
