The Summer Company is a faction that operates in their fortified island, the Summer Isle in Northern Blue.
As their name implies, they are a merchant Company that is the overworld's chief supplier and manufacturer of firearms and ammunition.
The Summer Company was founded when a blacksmith originating from the Central Luminant returned from his trip abroad, bringing with him the technologies of a foreign land, mainly the gun, or the common firearm.
They are one of the factions employed by The Authority.
They frequently come to blows with the Ignition Union, who steal their gunpowder and explosives for themselves.
In retaliation, they snuck into Miner's Landing and accidentally activated unfinished prototypes of the Union's security devices, the Mechalodaunts, making the cyborgs aggressively attack friend and foe alike.
They also buy and sell their guns to the Authority.
