Powers.
Machine Brain: Sage’s mind is not a literal computer, but is closer may be closer to one than any other organic brain on earth. It has granted her extremely fast processing speed, excellent multitasking and photographic memory. She has used this to develop a great deal of physical and mental skills, especially those related to espionage.
Telepathy: Sage is a skilled telepath. Her greatest ability is her extremely strong psychic defense, manifesting as a powerful firewall that can reflect psychic attacks back at less adept opponents.
Genetic Sight: Sage can get some insight into people’s genetics and potential by close contact. In the past, she has even been able to “jumpstart” dormant mutations in other mutants, though in most cases nothing happens.
History.
Tessa’s history with X-men started when she was just eighteen and met Professor Xavier in the mountains of Afghanistan. She was the first to find him after his legs had been crushed by a boulder, and he noticed her mental talents. He began to train her when the X-men were only a vague idea in his mind; and he found a place she could use her talents: espionage. Tessa became Xavier’s mole inside the Hellfire Club, rising to be a trusted advisor to their leader, Sebastian Shaw. She worked with Shaw and Emma Frost to outwit the telepathic billionaire Elias Bogan in a high stakes game of chance, forming a lasting grudge. Years later, Bogan would exact his revenge by kidnapping and torturing her, until she was rescued by Storm.
From then on, Tessa joined up with Storm and adopted the name Sage, becoming part of the team Storm assembled to search for a set of prophetic diaries left behind by the precognitive mutant Destiny. Her time with Storm’s steam saw encounters with foes such as the international terrorist Viper, the mutant hunting cyborg known as The Fury, and another showdown with Elias Bogan.
After M-Day, Sage moved to England and joined Excalibur. This diversion turned into a dimension hopping excursion with the Exiles, leading to a lot of experiences Sage is still processing. At various points she peered into the blackbox of a Celestial, visited a world where humans were wiped out by robots, had an interdimensional guardian dump a heap of cosmic knowledge into her head, and helped the team battle no less than ten evil alternate reality version of Xavier.
After all of the multiversal travel, Sage returned to Earth and laid low for a while, working in the background until recent events. With the establishment of Krakoa, Sage has become a key part of the island’s operations. She helps to manage the island’s gateway network, and is one of the members of X-Force, Krakoa’s department in charge of clandestine operations.
Story Arcs.
Cobwebs in the Attic
Tessa's mind has taken a lot of unresolved damage. She's done her best to patch over it, but incidents like the time The Fury hijacked her mind and turned her against her teammates or the massive information dump from Roma have created corners that even her machine brain doesn't dare examine. What is buried can never stay that way, and if it resurfaces at the wrong time it could potentially turn a key piece of Krakoa's security into an internal threat
