SOE Oberon Mobile Observatory
Sisters of Eve have long used this ship to lead disaster efforts her generous bays and medical facilities have long held the front lines against dispare in times of crisis.
Sisters are just as committed ot understanding the universe as they are to charity but in the times of war between the four empires the sisters donations are running dry forcing the Sisters to seek other means of providing for the refugees.
The solutions was to convert thier fleets of donated ships into astrometric ships. This continued to fund the sisters charity efforts and help sate thier wanderlust for the universe.
This capitol ships massive bays easily provided room for the complex sensors able to analyze any local phenomenom and tailor a complex program to reproduce the effects elsewhere for study.
Her conservatist design leads to have much less mass of a ship of similar size allowing her into wormhole space with cargo aboard easily.
When she energizes her scientific core the astrometrics computers and advanced sensors drain all other systems making her immoble for the duration while she analyzes the local space and possibly any phenomenom. The amount of energy generated would reveal to the entire system her location. However there is nothing in the system that will not be lit up when she goes off either revealing to location of everyone on the overview as well.
Despite this useful tool she is not a combat type capital ship and many of the designs nomrally afforded into a capital ship such as armored compartments and shield barriers makes her much more suspectable to damage. A dreadnaught can easily make quick work of an Oberon or a small squadron of battleships.
