Mordin

Mordin Solus was a top-notch professer who helped work on the genophage during the Great Galactic War when relationships between Salarians and Krogran were bitter, he looks down on his participation in the act but also views it as a "nessicary proceedure", saying that it was needed at the time, and if it wasn't deployed, the Salarians would probably be dead.

Mordins profession after the Great Galactic War is unknown, due to his inability to share information about it. It is assumed he worked as a professer in numerous places, taking up the profession of a doctor, scientist and even an actor. He took up residence in The Ulyssey after being rescued from Cloud City, he was found working on some experimental plans to kill some of the gangs in the city so he could get it to go back to normal, on the other side he was working on regular lab activities.

Once rescued and taken to the Ulyssey he took the job of being the ships medic, taking up residence in the medical bay and carrying out normal experiments, he has constructed the Collector Bug-Free suit for both commanders and squad members so they cannot be infected with the bugs that Collectors send out, causing bodies to freeze up. Unknown had sour relationships with Mordin due to Mordins curiousity about Unknown, and wanting to experiment on him to find out who and what he was, Unknown threw one of his machines at the wall next to Mordin before Commander Solaris came in and broke the fight up.

He's shown a large interest with Collectors, completely amazed by their body and abilities, he was seen in the container bay looking at the collectors body with Mona often.

 Health Concerns and Death 

After being sent on the mission to Alliance Colony Titan, Mordin and Mona were put in a pair and sent as the infiltration team, they traveled through the walls of the colony to get to Tillery, they broke into the base's gate and shot surrouding gaurds to get in, they took a secret passage and hotwired an elevator to have it take them up to Tillery, once they reached the top floor they were ambushed, Mordin took most of the bullets from Alliance soldiers, both were tied up and when they were found Mordin never regained conciousness, bleeding out when they got there. After returning to The Ulyssey, Mordin was rushed to the medical bay with Medge in charge, Medge told Solaris and Ebrown that he learned most of his medical skills from Mordin, beginning to grow on him and view him as a father figure. Medge watched over Mordin and said that he could pull through but its tough and it seems like a small chance.

After being on the Ulyssey for some time without the crew, the ships hull was breached and Collectors poured in, they reached the medical bay and ambushed Medge, causing him to hide behind the bed Mordin rested upon, the Collectors saw Mordin on the bed and fired numerous numbers of bullets into his body, causing him to go into shock and die seconds afterwards, Medge clipped a Collector with a tracking device before they left, and after they did he contacted Solaris and Ebrown saying that Mordin had died.

Mordin was given a proper funeral next to dead teammate Tara, they were both mourned by the crew and privately by Solaris and Ebrown. Mordin could've been saved by the Lazarus project, but there was not enough material to even fix close to what condition he was in.
