Sibling loss is among the most disenfranchised of griefs — often overshadowed by parental mourning, poorly supported by a culture that has fewer rituals for it, and carried in the strange loneliness of having lost the person who knew you longest.

This domain takes sibling grief seriously and holds its specific character.
