Tydo is a colonial security officer assigned to the minor research settlement of Cakapunnual. Quick on her feet and a "crack shot" with a rifle, she oversees routine security problems within the settlement. Her family moved to The Shoals after several stints on various different colonies.
Late in 2393, Tydo takes part in the local pursuit of an Orion smuggler. Equipped with a custom stun rifle, she was able to take at least three shots at the smuggler, successfully keeping him in check whilst the rest of the security force arrived at the scene. She is suspicious of a Starfleet-endorsed informant, Irasaph, whom claims to know the ins and outs of the Orion Syndicate and possibly hold ties to the Brekkian drug cartel Sky Blake is after.
