History of Clan Night: Crown of Sorrow

Clan Night: Crown of Sorrow is a 30-point triumph: complete the Crown of Sorrow raid with a team made entirely of clanmates.

How to complete

Bring a full fireteam from one clan and clear the raid. Per Gamer Rant, Crown of Sorrow launched in Season of Opulence (world first by clan Be Bold, June 2019). It is one of the Clan Night series (Last Wish, Garden of Salvation, etc.), whose requirement is a team of the same clan.

Unconfirmed: which seal it belongs to (likely the Reaper seal, but I could not open a source) and any reward. The score differs between a search snippet (15) and the game text (30).
