Eclipse is a faction dedicated to mutual aid and long-term solutions. They believe the ends justify the means. Each member is encouraged to operate as they think best, eschewing rules and regulations.
“The sun is 400 times larger than the earth's moon. And yet the moon can completely block out the sun's light. It's all about being at the right place at the right time and then doing whatever it takes.”
Eclipse operates both legally and illegally. They operate Penumbra LLC, which provides services powered by its members, as well as administrating their laundered assets.
Eclipse operate a protection racket in their territory, and are also involved in portal smuggling of substances like LSD and organizing illegal events like street racing.

Eclipse made headway into controlling parts of the city, before being stalled out by competition from the rival Faceless and the efforts of hero groups Clarion and Forerunners. Faced with increasingly bad odds, Eclipse made the decision to ally themselves with the Leeches, another small, new and especially vulnerable faction in Detroit. The Orphanage served as the alliance's shared base. Together they managed to stem the tide, claiming much of the Northwest of Detroit and extending their tendril throughout Detroit's underworld.
The event surrounding the Leeches' cape Fractal led to tensions between Eclipse and the Leeches. These were massively exacerbated by the Leeches performing an operation on the Orphanage's children to attempt to give them powers, resulting in the mutation of one of the children and the melding of the other two. These tension went so far as to bring Killsat to attempt to exact revenge on Leech by teaming up with cape factions outside the alliance.
After the death of Faceless' leader Nike, Eclipse started to expand their territory into former Faceless lands, mainly by new members Everyone and Kingsman. A push toward the similarly weakening Street Sharks was also made.

Everyone, Masquerade and Renegade participated in the investigation of the streak of murders that had parahuman perpetrators. During the Graveyard fight against Shadowdancer, Renegade lost his life.
Everyone, Kingsman and Masquerade participated actively in the united cape offensive during the Bug Invasion/Fog Incident. Masquerade lost his life in the first fight to shut down a fog portal.
After the invasion, Killsat grew increasingly distant with his trips to other earths, and without much noice Everyone took over as leader, after having been the acting leader for some time. The loss of prominent members led to a partial downturn, during which Eclipse still found new members and sustained activity outwards. Smother was active in the continued territory disputes with Horrorshow, but eventually left to join Forerunners for a time, until returning again later.
At various times Eclipse accepted members who where shunned or maltreated by their old factions, such as Onyx/Fiber, Gatcha and Smother.
Eclipse continued primary trough Everyone's efforts to keep Horrorshow at bay, while slowly absorbing territory from Faceless who had turned fairly inactive, but eventually all outward and aggressive actions ceased.
During the “Radioactive Sewer-creatures” incident, Everyone and Kingsman participated to some extent.
New Detroit factions formed during this time started chipping away at Eclipse territory, and eventually even the occasional resistance faded. “Type Two” eventually claimed some of the central downtown city-blocks that had been controlled by Eclipse for years.
Eclipse didn't show any sign of activity during the Cyborg Invasion, but at some point Everyone had seemingly returned from seclusion, after having supposedly met publicly both with Valiant Dawn's leader Impact and Phoenix's Xylilith in a short time-span.
