- "Welcome to Squad Dek-Nil can you taste the stars listen they surge they surge ohhhh we are the crescendo of a flea's dream let us not advance no but dance yes daaaance."
- ―Dek-Nil, singing to Chelli Lona Aphra
Squad Dek-Nil was a squad in the Accresker Penal Legion, the expendable fighting force of the Galactic Empire's Accresker Jail. The squad was led by Dek-Nil, a droideka reprogrammed by Doctor Chelli Aphra, who had been used as a hubdroid after being sent to the prison. During an attack on an EF76 Nebulon-B escort frigate, Dek-Nil arranged for the deaths of all the prisoners in his squad so he could save Aphra's proximity bomb to himself, also saving Lopset Yas in the process.
