Butterfly Cluster

Butterfly Cluster is the group of sectors in the West of Local Cluster.

You can see in the image below how players would see Butterfly Cluster while being in the sector Feroniside.

The sectors included in this cluster are:

• Beldian;

• Blaze;

• Buttery Pass-01;

• Coaliside;

• Deltonis;

• Enigiside;

• Feroniside;

• Gloschton;

• Helios;

• Silverancea;

• Theagous;

• Valence;

• Yehenous;

• Yiko.

The official name of the cluster is Butterfly and not "Buttery"; the name of the easternmost sector of this cluster should be "Butterfly Pass-01", but the allocated number of characters for that field did not allow more than 15 characters.

This is revealed in one of the Wikipedia pages of the game Fleet: "Fleet Universe".

Unfortunately, the Wikipedia page "Fleet Universe" has not yet been updated. Several planets of Butterfly cluster have been dominated since 2014 by the faction The Fishing Guild.

You can see below the News about Mirage FAB destructions:

At this moment, it is impossible to search in the Archive of Fleet News by using the name of a faction. But I was able to find these recordings in the "Buildings" section:

In the image below, we can see the most famous sector of Butterfly Cluster: Yehenous - as it was seen on 1st of December 2025.

The size of the sector Yehenous is 16 tiles horizontally and 16 tiles vertically.

There are 31 space-tiles which are hidden to the public view.

We can also see the "Welcome" message of the planet Yehenous Land (which is a Class-C Planet and it has a population of 40,000 citizens):

"Welcome! This planet is owned by The Fishing Guild! We are a relaxed group that believes in open trade. With access to the most powerful engines in the universe we travel from sector to sector vanquishing foes and acquiring the best deals the universe has to offer. If your interested in joining us, apply today!"

At the coordinates [0, -14], there is the wormhole to the sector Silverancea.

In the image below - taken on 1st of December 2025 - we can see the map of the sector Silverancea, which has a size of 16 space-tiles horizontally and 15 space-tiles vertically.

In the following image, we can see the status of the Class-M Planet Silverancea Prime on 1st of December 2025.

It is the same message from the faction "The Fishing Guild", but on a background with an orange sunset view and palm trees.

The Class-D planet Enigiside remained the only Neutral planet in Butterfly Cluster since 15th of April 2023. You can view the article dedicated to the planet (and sector) Enigiside at this link: https://www.gameofspacefleet.com/post/enigiside-the-only-neutral-planet-in-butterfly-cluster.
