Born into a Starfleet family, Logan spent many years with his parents
exploring the galaxy. By 2366, his father was a senior security officer
on a frontline base close to the Cardassian-Federation demilitarised
zone and his mother was a command officer on the base. There had been
no question that Logan wouldn't join Starfleet, and at the age of eighteen
he returned to Earth and started at the Academy, majoring in Engineering.
Having always had a 'knack' of fixing things that others only saw as
being un-repairable, Engineering was the obvious career path. However,
in his second year, the Dominion War started and his parents found themselves
in the front line. In 2371, just after the end of his third year, Logan
received the news that his parents had been killed during a Dominion
attack on the base. At first he was worried about his young sister Lana,
who had been with his parents at the time, but soon received word that
his sister was safe and returning to Earth.
With no other family to
take care of Lana, Logan was forced to stop his Academy training indefinitely
to look after Lana. Three years passed, whilst Lana grew up, and in
2374 Logan returned to the Academy to complete his training. It was
during his final year that Logan was noticed by Starfleet Intelligence,
who persuaded him to switch courses and offered him a posting at Starfleet
HQ when he graduated. As well as the Intelligence courses, Logan also
took additional courses in alien technologies and advanced piloting.
After graduating, Logan took up the offer to work at Starfleet HQ,
which meant that he could remain close to his sister until she was old
enough to look after herself. However, events took over and in 2379
Logan was asked to go on an away mission that took him to the area beyond
the nebula known as the 'Briar Patch'. He left in a small vessel with
three other Intelligence officers and nothing was heard from them for
over three months. The vessel returned to Federation space in early
2380, with only two survivors, both in stasis and the vessel on autopilot.
The details of his mission and the year after his return are classified
and compartmentalised. What is known is that Logan lost his right eye,
which was replaced with a cybernetic device.
After a year, Logan returned to active duty and moved from Intelligence
to Security, gaining a promotion to Full Lieutenant. He was re-assigned
to Utopia Plantia where among other things he was overseeing the security
during the upgrades of the New Orleans class vessels. By now his younger
sister had entered Starfleet Academy and Logan now felt that he could
relax and enjoy his career. In 2383, the first of the upgraded New Orleans
class vessels was ready to leave and Logan was assigned to the USS Taurus as Security Officer. After two years of exhaustive testing, the USS
Taurus was finally re-commissioned, and Logan received a promotion to
Chief of Security onboard the Taurus.
The USS Taurus was destroyed in
early 2385 and most of the crew were transferred to the USS Leviathan-B.
During his time onboard the Leviathan-B, Logan started a relationship
with the Chief Medical officer Rahel Kahfre. The USS Leviathan-B was
destroyed during a battle with the Karled, a race from the far side
of the DMZ between Federation and Mulluran space.
After taking a six month leave of absence, both Logan and Rahel returned
to Starfleet, but were assigned to different vessels, keeping them apart.
Unable to remain apart, both applied to be transferred to a location
where they could be together. Rahel was offered a position as Chief
Medical Officer for the Starfleet office at Lake Town Serenity, along
with a promotion to Lieutenant Commander. Logan was offered the position
of Chief of Security at Lake Town and both arrived in late October 2386.
Logan has a Cybernetic right eye with infra-red sights and a transceiver
which can transmit what the eye is seeing to others. This eye was replaced
during the period that Logan and the USS Thames was missing and there
is no explanation as to whom or why it was replaced.
Stronger than the average human, Logan is a martial arts expert.
At the end of 2386, Logan recieved a message from Commander Dawn Benson, a former lover and the mother of his daughter Bridie. Logan had known nothing about Bridie until 2376, when he'd recieved legal papers requesting that he allow a Lieutenant David Benson the legal rights to adopt Bridie.
At first Logan refused, feeling angry and hurt that he'd been kept out of his daughter's life. Eventually he realised that Dawn and David had far more to offer Bridie than he had and signed the papers. He never forgot about Bridie, but kept his distance allowing the Benson family to live their lives.
In December 2386, both Dawn and David Benson were killed in action. Dawn had named Logan as Bridie's new legal guardian, leading Logan to travel to Earth and bring her back to Serenity.
It will take both of them time to adjust to their new lives and responsibilities.
