After the teeming flood of refugees managed to free themselves from the Hall of Stars and the Waning Gate, war of rule quickly broke out across the now devastated nation. With chaos and unrest rife through every holding and many of the leaders of the caern-raths in those early days grabbing for as much land as possible to house their now immense populations, the Lughlinn of Manannan Port saw fit to quickly erect a title and a position to usher in a state of order and peace. A person who could unify the terrified and confused populace, who could marshal the Lughlinn Mór of the other caern-rath holdings and keep the human tribes from devolving into pure anarchy. That title was Ard Righ; the High King.
Some debate is made if the title was derived from the model of First of the Chieftains in the fwoarian lodges, or if it was a wholly original concept drafted out of desperation. Before, the human tribes had their archfey ancestors and ardruid forebears to see them through times of war and civil unrest. But, for whatever reason, the ardruids were gone and the archfey had left the tribes of man. Now, they elected a leader, a high lord to see the nation through its darkest hour. That man was Ard Righ Kead Caha the First.
Often overshadowed by his predecessor Ard Righ Mochuma, Ard Righ Caha was a humble Lughlinn history tells us and did not initially desire the role of Ard Righ. But, as the violence and desolation of the very first years of the War of Spears began to only escalate, he eventually accepted his position. By all accounts he ruled with a firm, but honest hand, simply seeking to bludgeon the human tribes into a more ordered era. His initial attempts were incredibly successful; having forced Roan-Rath and Foalport to capitulate in the first 30 years of his reign. By the time of his death, he was in his mid-50's, with no signs of slowing down. Truly, the blood of the ardruids was still strong in him as his face showed little aging and his sword-arm remained strong.
He ultimately found his death at the North-West edge of the Sea Bastions, when an errant spear thrown by a Skilti struck him from his position behind the Lughlinn ranks. He died there on the field and in their great mourning the Lughlinn of the Sea-Guard secreted away his body to the depths of Manannan Ports crypts where they guard over it to this day.
He was succeeded by his daughter Ard Banríon Caha, who married Lughlinn Malucnus and become the second Ard Righ who continued to struggle for a united inisa. Although it would never be achieved in their, or their children's', lifetimes.
While he is often given less mention than his descendant, many scholars view Ard Righ Caha as something of a patron of the human tribes. Its hard to say if without him the inisa would exist as they are, or if mankind would have drowned itself in its own violence and turmoil. Whether his actions by unifying the southern coastal caern-raths was instrumental in concretely stabilizing the country as a whole some 200 years later, or simply a moment of glory in a dark age. What is known is that he was the first in a line of powerful men and women, his acts of heroism on the fields of battle in an era where the common man had no signs or symbols of hope to look to are often whispered stories, as if in prayer, with some people even conflating the first Ard Righ with the ardruids. In some regional customs he is an ardruid, as the stories are told; Ard Righ Caha, Ardruid of Order and Royalty. A fitting legacy to the first of the kings of the country.
