FireGraySilver

FireGraySilver is the poly ship between Firestar, Graystripe and Silverstream from the Warriors fandom.

Canon
Silverstream rescues Graystripe when he accidentally falls into the river, and the two start meeting in secret, having fallen in love. During a battle, Graystripe's friend, Fireheart refuses to attack Silverstream, causing Tigerclaw to suspect he is a traitor. Despite Mistyfoot and Fireheart pressuring them to stop meeting, they are soon expecting kits, and Silverstream is confident that the kits will be accepted as her father is Clan leader. However, the kits come early, and Silverstream doesn't survive. RiverClan demands ThunderClan give them the kits, and Graystripe prevents a battle by allowing this, but he joins RiverClan to help raise them. Moons later, Silverstream appears in StarClan, giving Firestar one of his nine lives, the gift of loyalty and to know what is right.

Fanon
FireGraySilver is an extremely unpopular poly ship, barely getting any fanart or fanfiction. There may be some minor mentions of the ship in fan videos, but nothing too much.
