After Juhraya found itself in Cardassian territory, Macias was dragged from his bed and beaten. The authorities did nothing other than to agree with him that it was an unfortunate situation. Soon after, he left his colony and joined the Maquis.
Lieutenant Ro Laren was sent by Captain Jean-Luc Picard to infiltrate his cell in 2370 after returning from two years of training in Starfleet Tactical. Ro sympathized with Macias and the Maquis for their struggles and the two became very close in a short space of time. Macias was fond of particularly spicy hasperat, after being introduced to it by a Bajoran friend who was later killed during the Occupation of Bajor. Macias reminded Ro very much of her own father, who was also killed during the Occupation when she was just a child.
