Dumb
Moving towards the perimeter of the anomaly, the 2 objects closed towards the liquid layer. Upon reaching the anomaly perimeter, the 2nd tube-shaped object began to spin rapidly, as it spun pulsed waves of energy radiated out from it and spread through the local area, as if the object was scanning the local area for other ships.
Seeing that there were no other ships about the objects both suddenly began to rise as the hole they emerged from enlarged to reveal their true origin...

A ship rose from the void, its curved and smooth hull colored in black and burgundy. Upon its forward deck a bridge structure rose smoothly upward, its sides marked with a symbol emblazoned in gold with its top holding the objects from earlier.
Upon emerging 4 hatches situated behind the bridge revealed themselves before momentarily disappearing in a cloud of exhaust as they launched what appeared to be missiles However, these missiles acted strangely as they sped quickly into the anomaly radiating pulsed waves of energy into the anomaly and between themselves.
