House of Winter
From Destinypedia, the Destiny wiki
Prior to arriving in the Solar System, the House of Winter was one of many Fallen Houses struggling to survive in the wake of a cataclysmic event known as The Whirlwind. In the aftermath of the fall, Winter were said to have warred with the House of Scar. There is evidence they were present at Caracas during the Collapse. They settled in on Venus, showing interest in The Archive of the Ishtar Academy, seeking to plunder the Golden Age technology within, as well as towards the nearby Vex Citadel.
Enemy of Humanity
Years later, when the Kell of Kings sent out the call to attack the City, Draksis, the Kell of Winter, answered, uniting with the House of Devils and Kings. In the ensuing carnage that was the Twilight Gap, the united Fallen were smashed against the City walls and forced into retreat. Reeling from the conflict, Winter once again was forced into scavenging Venusian ruins and coming into conflict with the Vex. It is believed that some time after the Gap, Winter's Servitor God, Simiks Prime was destroyed, though proof of its demise remains elusive. Draksis continued to war against the city, raiding jump-ship convoys using guerrilla tactics, causing Cayde-6 of the vanguard to personally raise the bounty on him.
Winter staged an assault on The Archive, attempting to plunder Golden Age secrets from the Ishtar Facility. The attack was lead by Grayliks, Winter Baron and further supported by Simiks-3, a Winter Servitor of significance. The raid was thwarted by Guardians however, who destroyed Simiks-3 and killed Grayliks, securing The Archive for The City. Sometime thereafter, the Vanguard received word that Wintership Simiks-Fel was on the surface of Venus and began a mission to assassinate Draksis. Fighting through Draksis' Kell's Guard, a Guardian made their way onto the Fallen Ketch and faced Draksis in his throne room, killing him and beheading Winter's Leadership. Afterward, perhaps as an attempt to replace Draksis, Winter enlisted Taniks, the Scarred to break into the Prison of Elders and retrieve Aksor, Archon Priest. However a fireteam of Guardians quickly ended him and the Fallen which broke him out, leaving them leaderless.
During the Wolf Rebellion, the House of Wolves' rampage across the Solar System, Skolas, Wolf Kell has successfully pressed into service the demoralized House, assimilating them and declared himself as the Kell of Kells. After the start of the Rebellion, Guardians fought against Winter, salvaging ship links from them, in order to track Skolas's movements, leading The Reef to discover his deployment of The Silent Fang to Earth. Winter forces were also present in aiding Skolas to break through the Vault of Glass and capture the Vex technology. They were also found above The Citadel with Wolf forces, but would cease to follow Skolas after he was captured by the Reef and Guardians, and killed in the Prison of Elders, ending the Wolf Rebellion and leaving Winter leaderless once more.
The Taken War
Variks, The Loyal at some point was in negotiations with Grayris, Baroness to leave her house, however she would succumb to Oryx's Taken. During the Taken War the House of Winter managed to take advantage of the Reef's disorganization to break into the Prison of Elders and retrieve another Archon Priest. However the Taken on Venus attacked and scattered their forces, Taking the Archon in the process, turning him into Nixis, Hunger of Oryx. Guardians managed to destroy Nixis, ending Winter's second raid on the Prison as poorly as the first. 
Withdrawal and Unification
Like the rest of the Fallen Houses, the House of Winter completely abandoned their territories on Venus, and united with the rest of the Fallen under the newly formed House of Dusk.
Unlike other Houses, Winter does not seem interested in creating new leadership from within their own ranks after the death of their Kell, Draksis. The extent of the strength of their current leadership as unknown, due to there being no mention of their House Archon, and the rumors of their Prime, Simiks Prime, being destroyed.
They have made two attempts to recruit outside nobility to join their house, both former Archon Priests, with unknown intentions for their new roles within Winter. In addition, they were the only Fallen House that chose to follow Skolas during the Wolf Rebellion.
