Sekat

Sekat is a Salarian informant on Illium and one of Liara's contacts.

Lair of the Shadow Broker
After being given the data about the Shadow Broker, Liara returns to her apartment and contacts Sekat. He says that it was tricky, but he narrowed the Shadow Broker's Base to a cluster, maybe even a system. He expressed concern on what could come out of all of it, but Liara told him to relax and she will meet him in a few hours at his office in the Dracon Trade Center. She recorded the call before she was nearly killed by one of the Shadow Broker's assassins, and left it in one of her Prothean relics for Shepard to find. Her apartment was under investigation by Illium police officers and Tela Vasir, a Spectre. Shepard and Vasir find the backup disk and they play it on her terminal, then depart to the Dracon Trade Center. Shortly after arriving, the Center is damaged by explosives the Shadow Broker's agents put shortly after Liara entered the building. After fighting through the Shadow Broker's forces in the building, Shepard learns that Sekat was killed by one of the Shadow Broker's agents. Tela Vasir reveals to be the assassin that tried to kill Liara, and she killed Sekat to take his data.
