At some point, the airship began to descend and change shape. That was a scouting-type airship. Good at avoiding detection like radars and other methods, not to mention it was very silent. Linfel's group ad to stay pretty close to each other, and there was almost no space remaining inside.
Yet, all of the airship's abilities mattered little... except for a single one. It could get very small, packing those inside even closer. That one ability was the main one that would help it get behind enemy lines.
*Zush!*
Suddenly, the little light that could be seen from outside disappeared, and the airship disappeared underground. It didn't have the ability to drill. Instead, it entered a cave near a mountain, quite far away from the rest of the action.
The pilot skillfully controlled the airship while following a route pre-determined through the tunnels underground.
*Splash!*
