A reincarnated soul from Earth who retained the memories of his previous life, Thaddeus was born to aristocracy in the Eastern Greywell Archduchy on the world of Valerium, a fantasy-type world of swords, magic, monsters, adventurers, kingdoms, and other forms of nobility. He is the son, heir, and only child of Archduke Rutherford Greywell and his wife Dorothy. Tested at birth and found to have high aptitudes for swordplay and magic with attributes focusing on speed, agility, dexterity, and intelligence, he began training early with great enthusiasm in the arts of fencing and magic. Now at age 12 and already a top class adventurer, he remains composed, competent, intelligent, and unfailingly polite, the perfect picture of high society etiquette blended with a thirst for adventure. His swordsmanship is exceeded only by his magic, boasting an arsenal of spells that include offensive and defensive ice magic, healing, status recovery, holy-based purification, and support spells, all blended into a seamless whole that leaves no weaknesses uncovered.
