SUMMARY
→	A mostly untouched H-Mass System 176Ly from Colonia. Notable for its trinary black holes (two of which scare you on approach) and a rare Taylor's Ring around a gas giant (ring 10% of gas giant width).
DESCRIPTION
→	A high-mass system hidden in the star density of the Colonia region. Though it is an uncommon sought-after H-mass system that doesn't dump all mass into a Wolf-Rayet, it only has a visitor's list five names long. Commanders entering the system can expect to be surprised by the close binary of singularities upon entrance that can force the FSD to emergency drop without quick evasion or hyperspace dethrottle. Discovery scanning will populate the system map with an additional black hole as well as a few ringed stars and gas giants, as well as a few landables. ![System Map First Half](https://imgur.com/Mmbe2ZS.png) ![System Map Second Half](https://imgur.com/HDAsXo5.png) Due to the proximity of the black holes to each other, the gravitational lensing effects combine to make a hole in space-time visible from anywhere in the system. ![Main POI Image (tertiary black hole not shown)](https://imgur.com/H6zNFmN.png) The system also contains six landable atmosphereless planets orbiting brown dwarfs with rings, potentially creating striking views for those willing to manipulate the camera suite. Most are even unmapped, giving the opportunity for explorers (or non-explorers, given the close distance) to get their names registered with Universal Cartograhics. Unfortunately none of the rings of the system contain any notable valuable materials, unless you're in search of minerals ending in -ite contained in the dozen hotspots scattered around. The dwarfs boast wide rings stretching to the exclusion zone, although its a common sight throughout the galaxy. One ring in particular, the only one orbiting a gas giant, is special. The width of the ring is only 9.8% of the host bodies' diameter, making it a quite rare Taylor's Ring with more then a few uninteresting hotspots. Another Taylor's ring is close by in the populated system Rodentia Petram.
