Keepsake

"It's just... It's sorta like a charm..."

- Parisa

A keepsake, memento, or souvenir is a unique item that a person holds to be of special importance, reminding them of a person, place, or event. They range from photographs, toys, trinkets, and other memorabilia. Many are kept out of memory of the person who gave it or originally owned it. Being personal objects, they are mostly unrecognizable to outsiders. Within the UNSC Armed Forces, soldiers often pass along their dog tags as keepsakes for their comrades to remember them by. Although generally considered an unseemly act, and in the case of the United Nations Space Command, against protocol, some Covenant and human soldiers were known to keep souvenirs from fallen enemies as war trophies.
