Editing Cycle 15/Ruleset Draft (section)

== Board ==
Each player has a location (syn. "current space"), which is a space. For a player to "move to" a new space, other than their current location, is for their location to become the new space. Initially, or if a player would otherwise lack a location or have indeterminate location, a player's location becomes the initial space (as elsewhere defined by the rules, or otherwise the oldest-created existing space) if possible.

=== Spaces ===
A space is an entity. Each space has an identifier, which is an integer unique among spaces. An attempt to create a space with an invalid or duplicated identifier fails, rules to the contrary notwithstanding. The space with identifier N is known as "Space N".

A space with identifier 0 always exists, and is created immediately if it does not. This space is the initial space.

Each space has a type. The possible types are described by other rules. Initially, or if a space would otherwise lack a type or have indeterminate type, a space's type becomes Blank.

==== Blank ====
"Blank" is a type of space. Blank spaces have no effect that occurs when a player lands on or passes through them.

==== Crystal ====
"Crystal" is a type of space. When a player lands on or passes through a crystal space, they gain 1 crystal.

=== Connections Between Spaces ===
Each space has a set of successors, each of which is a space. If such a set would ever contain non-spaces, or if one of its elements ceases to exist, the set is modified by removing any offending elements. Each space initially has no successors (that is, its set of successors is empty).

A space is said to "precede" each of its successors. A space "succeeds" (syn. "follows") each space that precedes it.
