April, 588: Born and raised in a small town at the time named Trefynwy.
March, 601: Apprenticed to the local apothecary and began his studies| August 610 Battle came to Trefynwy and Gwydion took the call for warriors to fight off the Saxons from invading the Welsh Brethren to the South.
September, 615: Routed, injured and disheartened from the Battle of Beandun Gwydion returns to Trefynwy with a new limp and a dark outlook on life as the Saxons continue to take Welsh land on the south west peninsula. This is when he met up with his mentor Conchobar. Or Conor if ran into in this era. For some reason Conor took a liking to Gwydion and began to guide him towards becomming a Purified Immortal.
625-630: Perfected his formula and taken his potion to become Immortal, Gwydion finally succeeds at becoming a Purified with Conor's help. It was in this time that Gwydion met the woman now known as Rebel and learned of the Reborn. He's given his oath to this immortal soul to maintain her tomes and books while he's still among the physical world taking the tome into safe keeping when she's nearing the end of her life each cycle.
630-680's: Returned to the glory of his 20's without any lasting injuries, Gwydion begins to help the Welsh fight the Saxons.
8th Century: Tired of war, Gwydion has left Wales and England for Europe beginning his travels and study of the world.
9th Century Gwydion returns to Wales and returns to the fight with the valiant attempt at keeping the English from taking over Wales.
10th and 11th Century: Discovered to be a supernatural beast having been bound and burnt at the stake he returned to life soon after thinking the coast was clear only to have been found to be alive again by the same zealots only to be killed, staked through the heart, chained, shackled and buried in a coffin in an unmarked grave in the middle of nowhere... It took him nearly a hundred years to find and talk Rebel's incarnation into digging up his body to release him from this torment.
12th-16th Century: Began traveling the globe again starting in Spain and making his way through all of Europe and towards Asia as he became a traveling merchant never visiting a town more than once a generation.
17th Century: "New World" means new areas to explore and travel on, so Gwydion moves to North America at this time - and begins to explore and travel starting in Maine. Although at this point he's wanting to return to having roots again and begins to explore generational taverns and bars that he would stay at for no more than 10-15 years before moving between them and never returning back to an area where he had worked for at least a generation or two.
18th Century: Having explored the Eastern Seaboard of North America Gwydion begins to travel west although when the opportunity comes up for him to engage in battle with those British troops he joins the side of the Colonists and wages war on the Crown of England once again. Once the Revolutionary war was over Gwydion returns to traveling west establishing taverns, saloons and inns in the towns along the way.
19th to 20th Century: California was discovered and despite the beautiful scenery and the epic views Gwydion longs for something closer to home. So east he goes along a different path but back towards the east. Until he settles on a spot near Maine deciding this is where he'll live for a long while.
21st Century: Hard to believe but it's almost easier to blend in and vanish with the sizes of the cities these days so Gwydion's spent the last century traveling around the bigger cities of Maine until settling in the area of Fallcoast where he'd first arrived in the 'New World'.
