Sankta Maria's sensors detect a ship entering and exiting sensor range.

Eventually an image reveals the ship to actually be five different ships, although the warship leading them is a large ship, although not probable to be the largest...
Its weapons are kinetic based, and so its impossible to tell if its weapons are active or not.
If it has shields, they are clearly see-through...
Notably the ship is not flying as fast as it could be, probably to let the smaller ships keep up.
It makes no attempt to send a transmission to the planet or anything in orbit as it continues to go around in a "circle"...
