Add a “Shard Shifting” rule containing:

Shard shifting allows Tessers to change shards of their own affinity to shards of a different affinity. To shift N shards, a Tesser must remove those shards from their list of shards and write a story post with a [Tessered X] tag (X being greater than or equal to N) that specifies they are shifting N shards. When the shifting action is finally performed, the Tesser gains N shards of the same affinity as the orientation of the Tesseract at that time, except if the orientation has the same affinity as the Tesser in which case the Tesser can choose which affinity their shards are being shifted to (all shards must be shifted to the same affinity). If for some reason the action is not performed, the shards are lost. At any given time a Tesser may only have one post containing a shifting action.
