L-星团

孤悬于巨型椭圆银河系之外的L-星团

L-星团（L-Cluster）是孤悬于银河系东北方向的一个星团，通过常规的超空间航道、试验性亚空间导航或跃迁引擎等方式无法访问。L-星团中的某些天体上包含一种独特的战略资源： 纳米机器人（Nanites）。如果在L-星团内建造环形世界，则不适合居住的部分可能会获得 纳米机器人（Nanites）矿藏。

L-星团中发现特殊事物的种类在游戏开始时就已经决定好了。因此，在访问L-星团之前重新加载以前的存档不会改变结果。

L-星门

一些黑洞星系是 L-星门（L-Gates）的发源地。这些经过大幅修改的特殊星门无法使用普通的  星门激活（Gateway Activation） 科技激活。第一次遇到L-星门时，L-星团条目将被添加到情报日志中，这需要收集7个L-星门见解。可以通过调查某些异常现象、打败某些敌人、研究可重复稀有科技  L-星门认知（L-Gate Insight） 或每隔10年向策展人组织花费 -5000  能量币（Energy Credits）以获得一个L-星门见解。一旦某个帝国获得5个L-星门见解，其他帝国将收到通知。

玩家可以花费50 稀有文物（Minor Artifacts）来获得一个L-星门见解，冷却时间为10年。

一旦收集到7个L-星门见解，将可用于研究  L-星门启动（L-Gate Activation） 科技。帝国必须拥有一个带有L-星门的星系才能访问L-星团。最后，将添加一个特殊项目来激活L-星门，科研船需要180天才能打开星门。

一旦第一个L-星门被激活，将发现四种事物之一，权重如下：

结果	概率	发现后是否开启全部L-星门
灰蛊风暴（Gray Tempest）	35.7 %
德萨努协和国（Dessanu Consonance）	21.4 %
小灰（Gray）（一片静寂）	21.4 %
L-星龙（L-Drakes）	21.4 %

一个银河系中最多可以存在10个L-星门，并且无法建造新的L-星门。L-星团中只有一个L-星门，位于 终端出口（Terminal Egress）星系中，因此银河系中的任何L-星门都将连接到终端出口星系中的同一个L-星门，但终端出口门可以用于移动到银河系内的任何L-星门。

与常规星门不同，敌人星系中的L-星门可以在战争期间使用。

在激活L-星门之前，完成的哨兵阵列将不会提供L-星团的可见性。在L-星门激活后，它将提供L-星团的可见性。

灰蛊风暴

Gray Tempest emerging from a reactivated L-Gate

A common outcome of the L-Gate activation is an invasion from the L-Cluster. All L-Gates in the galaxy except the first one activated will open at the same time and bring an invasion force. In a tiny galaxy with only one L-Gate the empire that activated it will endure the invasion instead.

If a Gray Tempest fleet bombards a colony until it reaches 100  破坏度（Devastation） it will turn it into a Nanite World. If the colony is a habitat or a ringworld segment, it will be destroyed.

Nanite fleets are composed of one titan and 5 cruisers all equipped with a few energy weapons and numerous strike craft. Their energy weapons deal -25% damage to shields and double damage to armor, their strike craft ignore shields and 66% of armor and their titan weapons ignore all shields and armor. Therefore point-defenses are necessary, preferably Flak Artillery, and  水晶复合镀层（Crystal-Infused Plating） or  水晶锻造镀层（Crystal-Forged Plating） components and to a lesser extent shields will help. Nanite ships have equal amounts of tier V armor and shields, and their special strike craft can’t do point defense, so the best offensive weapon would be Torpedoes. Due to the huge number of strike craft that nanite titans carry own strike craft are more useful at fleet defense than offence.

The Gray Tempest home system contains a factory station twice as strong as the usual fleet which will create a new fleet every 10 years. If the factory is destroyed, all Gray Tempest ships will dissolve and all Nanite Worlds will get the Terraforming Candidate planet modifier.

德萨努协和国

Another possible outcome of the L-Gate activation is finding an empire called the Dessanu Consonance inhabiting the entire L-Cluster. Upon discovery the Dessanu will provide the empire that opened the gate +1  活体金属（Living Metal）,  异星天然气（Exotic Gases）,  稀有水晶（Rare Crystals） and  易爆微粒（Volatile Motes） as well as the Living Metal technology if it hasn't been already researched. Their only request is that no ship will enter the factory trinary system at the heart of the L-Cluster and that they are not asked about the Nanites. The Dessanu will never leave the L-Cluster even if they become hostile, nor will they build new fleets.

Each time a ship or fleet enters the factory system the Dessanu will demand that it leaves within 60 days. Refusing to do so or inquiring too much about nanites will make them hostile, as will attacking them.

Each Dessanu system contains at least one Gaia World. However, if a planet is successfully invaded and occupied it will turn into a Nanite World with the Terraforming Candidate planet modifier. All armies will safely retreat back in orbit. If the factory is destroyed the same will happen to all Dessanu worlds.

小灰 

If the L-Cluster is abandoned a random Nanite World will have a Level 3 Surface Signature anomaly. Investigating it will reveal a nanite entity taking the form of a member of the species discovering it. Asking it to join you will add Gray to the Contacts menu. Gray can take one of three forms at any time (except if it is in battle or merging state):

• Governor Level 10 leader with the Nanite Entity trait
• Nanite Titan ship (around 40k fleet power)
• Nanite Warform army (around 1k army strength)

Should Gray be destroyed it will merge back and reappear in 10 years.

This outcome leaves only one L-Gate activated, all the others coming online afterwards one at a time every one or two years. This gives the empire that activated the first L-Gate a significant head start, especially if opened in the early game.

L-星龙

The only outcome of the L-Gate activation seemingly unrelated to nanites is the spawning of L-Drakes. Each L-Gate in the galaxy will activate and bring an L-Drake which will travel to a random system three hyperlanes away and nest there. It will not be hostile even if its nesting system is claimed. If an L-Drake is attacked all L-Drakes will become hostile towards the attacking empire but each L-Drake killed adds a moderate reward of  影响力（Influence） and  矿物（Minerals）. If the empire that opened the L-Gate takes this stance it will also gain moderate  Engineering and  社会学研究（Society Research） research for each killed L-Drake and discover that the L-Drakes are nanite constructs. L-Drakes fight identically to the Young Drake from the  星神兽故事包（Leviathans Story Pack） DLC.

If the empire that opened the L-Gate enters a nesting system with a science ship it will have the option to start a special project to tame the L-Drake residing there, gaining control of it. The option is not available if the empire is  极端排外主义（Fanatic Xenophobe） or genocidal.

This outcomes leaves all L-Gates activated and leading to an abandoned L-Cluster, allowing everyone access.

结果

L星门的结果在星系生成时就已经作为全局flag设定好了，所以存档SL并不会改变结果。如果在非铁人模式控制台输入以下指令则可以获知开启L星门的结果。

effect if = { limit = { has_global_flag = gray_goo_crisis_set } custom_tooltip = "Gray Tempest"}#灰蛊风暴
else_if = { limit = { has_global_flag = dragon_season } custom_tooltip = "L-Drake" }#L-星龙
else_if = { limit = { has_global_flag = gray_goo_empire_set } custom_tooltip = "Dessanu Consonance" }#德萨努协和国
else = { custom_tooltip = "Gray" }#小灰

从故事叙事/角色扮演的角度来说，小灰事件结果中显示给玩家的文字描述了德萨努协和国的事件，而德萨努协和国又描述了灰色风暴的事件。 但是这仅仅是从故事叙述的角度来看待事件，正如上文所述，结果在星系产生时已经确定，在游戏更早的阶段启动L-星门并不会触发“更早的事件”。
