Imprisoned

Imprisoned was a virtual representation of one of Arno Dorian's genetic memories, relived by a Helix initiate through the Helix Navigator.

Description
Arno was imprisoned in Bastille, alongside Pierre Bellec and Marquis de Sade. There Arno met Bellec, and spent his time training with him until the day Bastille was besieged by revolutionaries and together attempted to escape.

Outcome
Arno and Bellec reached the balcony of Bastille, where Bellec gave Arno a token which Arno would need once he decides to join the Assassins, before jumping off. Later, as the guards close in, Arno jumps and escapes the prison.
