Hostile.

Ava woke up to the sound of alarms blaring in her ears. She quickly got up from her bunk, adrenaline coursing through her veins. She ran to the control room, where the rest of the crew was gathered around a console, frantically trying to pinpoint the source of the alarm.

"What's going on?" Ava asked, out of breath.

"We've got an intruder on board," said Ethan, one of the security officers. "They breached the airlock and are making their way towards the engine room."

"We need to stop them," Ava said, determined. "We can't let them sabotage the ship."

The crew split up, some heading toward the engine room to intercept the intruder, while others stayed behind to monitor the ship's systems. Ava ran towards the cargo bay, where the intruder was supposed to be headed.

As she approached the cargo bay, she could hear the sound of footsteps echoing off the walls. She took a deep breath and readied herself for a confrontation.

When she reached the cargo bay, she saw a figure in a spacesuit rifling through the crates. She recognized the logo on the spacesuit - it was one of their competitors.

"What are you doing here?" Ava demanded.

The intruder turned around, startled. "I could ask you the same thing," he said, pointing a weapon at her.

Ava raised her hands in surrender. "We're not here to steal anything. We're just passing through."

The intruder hesitated, then lowered his weapon. "Fine," he said. "But stay out of our way."

Ava watched as he disappeared into the shadows, then let out a sigh of relief. She knew they had narrowly avoided disaster.

After the incident with the intruder, the crew was on high alert. They doubled their security measures and increased their vigilance, knowing that their competitors would stop at nothing to sabotage their mission.

Despite the added pressure, Ava and her team managed to make good progress on their journey. They passed through a series of strange and beautiful worlds, encountering all manner of strange creatures and wonders.

One day, they came across a planet that was covered entirely in water. Ava and her team donned special underwater suits and descended to the depths, eager to explore the alien ecosystem.

As they swam through the murky waters, they saw all manner of strange creatures - giant squid-like creatures with glowing eyes, schools of shimmering fish, and towering kelp forests.

But as they delved deeper, they began to sense a strange presence watching them. They looked around nervously, but couldn't see anything. Suddenly, they heard a low rumbling noise, like the growl of a massive beast.

Ava signaled to her team to return to the surface, but as they began to swim upwards, something grabbed hold of Ava's leg. She felt a sharp pain and looked down to see a massive tentacle wrapped around her.

She struggled to break free, but the tentacle only tightened its grip. She could feel herself being dragged deeper into the water, towards an unknown fate.
