From Citizen Sleeper Wiki
The Yatagan Data is a type of data players encounter during gameplay of Citizen Sleeper.
Description[edit]
The Yatagan Data is a data cache skimmed from Yatagan hardware. The data can be sold to Havenage for 10 cryo or, alternatively, they can sell the data to Castor, but players must exchange 5 data items in exchange for 1 Stabilizer. Thus, players may weigh if it is worth selling the Castor or Havenage — players may take into account that they can also buy Stabilizers from Sabine, but this comes at more expense.
