Thandanar (Sindarin: 'Shield Brother') Helcharon, son of Aglarion Helcharon and Naurien of Lossarnach, is a Knight of Gondor and the middle of three children in a knight's family. Growing up, Thandanar would be trained to fight by his father along with his uncle, Pelingildir. He, much like his siblings, would experience much of the court intrigue among the higher Tiers of the White City.

From avenging the death of his father at the hands of raiding Corsairs in Belfalas, to fighting under the command of the Steward’s sons, Boromir and Faramir, against Mordor and its allies from crossing the Anduin at Osgiliath (with support from the Rangers of Ithilien); from defending his home city of Minas Tirith from besiegement by Mordor, to making a stand with Host of the West at the Morannon, Thandanar has had an eventful military career, one which as left visible reminders upon him. His signature face scar came from an orcish blade came from the retreat from Osgiliath, whereas the loss of his right hand would come from a troll’s hammer at Morannon.

His sword, Ragminuial (Sindarin: 'Dawn-Breaker'), is forged from the steel of the blades of the Corsair Captain Blood-Eye, his father’s killer. When the vengeance wrought in Blood-Eye’s demise brought Thandanar no joy, he cremated her and took her weapons to be reforged into a weapon that would remind him that that vengeance does not mean justice. Thandanar would be bestowed the title Knight of Gondor by his patron, Cuandir Alagosion, the Swan Knight whom he squired for in Dol Amroth. His nickname of "The Black Swan", amongst the warriors of Osgiliath, comes from his use of armour made in the style of that of the Swan Knights of Dol Amroth, a memento itself of his time there, and his surcoat that remained in the colours of Minas Tirith. Though this originating in jest, it would become a mantle for Thandanar,  who would later be known to in military circles as "Moralphon", for his leadership and putting the lives of his fellow men before his own.

Sometime after the War of the Ring, Thandanar would decide to explore the lands beyond Gondor's boarders. The road took him north to King Elessar’s new Kingdom of Arnor, where he hopes to learn the history of the area and help the Free-People, just as he had done in Gondor. In the present day, Thandanar may be found exploring Middle-Earth with his loyal Charger, Maethoriel, acting as a Knight-Errant and a helping hand. He also wishes to gain insight into the history of lands elsewhere, largely through tomes and exploring ancient ruins. He records his findings in journals, with the hopes his findings will help the Houses of Lore in Minas Tirith.

Recently, Thandanar became Master of the Order of The Northern Watch, once again taking to using the moniker of Moralphon.
