[spoiler]I propose we use the tag "g5 unity crystals":/tags/g5+unity+crystals or "unity crystals":/tags/unity+crystals for the crystals from the movie. Ideally this would be temporary until we get an actual name for them but the tag itself would imply the tags "earth pony crystal":/tags/earth+pony+crystal, "unicorn crystal":/tags/unicorn+crystal, and "pegasius crystal":/tags/pegasius+crystal respectively.
