Ark

The Ark is an object currently submerged in the remains of Droid Town. Its recovery is the goal of both HackNet and Moirai Enterprises

History
The object that would be later referred to as The Ark is a massive experimental satellite preceding Elle that would assist in the network of Droid Town. Before it was successfully launched, it is assumed that HackNet hacked the systems of Humandroids inside Droid Town, which resulted in Satoshi Sakurai detonating all of the HumaGears in Daybreak before they could escape and sinking the Ark in the process.

Recovery
Darren is planning to recover it by gathering data from hacked Humandroids. Meanwhile, Becca Fox's boss proclaims that Elliott Industries' SD Programmer data, which were supposed to be lost in the Zero Day Event 13 years ago, are the keys to its recovery.

According to Darren, once enough post-battle data has been collected from the SD Hackers the Ark can be restored and be used to incite all Humandroids to go berserk at once.
