Simple. It's a container that you can bury anywhere you wish. Place meaningful items in it (books, items with character names, etc), pick a spot to bury it with a shovel, and if someone digs in that spot in the future, they will dig up the capsule. Upon "sealing" the capsule, you can engrave it with anything you wish (like Valentine's bears). It will also record the name of the player who seals it, and record the date sealed. After unearthing a sealed capsule, you can choose to open it, bury it again, or just keep it as is. If you choose to open it, a warning message appears, letting the player know that when the seal is broken it cannot be closed again. After breaking a seal, you can take the items inside and keep the capsule as a momento. The capsule can be used as a regular container, but due to the broken seal, it cannot be buried again (this prevents the original date from being altered). I suppose maps could be made for these, but that'd make them more like buried treasure chests. Please post suggestions and thoughts.
