Agthallion was born Into a noble Noldorin Family, on the year the building of Gondolin was finished. He had a older brother named Agfaroth, taller and stronger then Agthallion, As brothers these two did everything together, hunting, forging, learning, war.

His Mother, Taurwen was the fairest of all the elves within Gondolin when she sang upon the walls of Gondolin all the city stood still and all was quiet, as if she cast a spell over all that listened.

Herulaure, his father, Tur of the house of Turthoron, was greatly respected as a warrior and leader, of one of the mightiest houses of Gondolin. His speeches would rally warriors like no other could, it was once said that Tur Herulaure could win a battle with only few of his personal guards against numerous orcs thanks to the speech alone.

In the Year 510 of the 1st age Agthallion and Agfaroth accompanied by 30 Warriors of Turthoron traveled to the forest of Doriath for festivities. Whilst they were away Gondolin was besieged.  Taurwen and Herulaure both fell with Gondolin.

From that day the two brothers swear an oath to kill any that would do harm to there kin. Agfaroth becomes Tur of Turthoron and together with Agthallion they rebuild there army that was lost during the fall of Gondolin.

By the Year 545 of the 1st age there Turthoron surpassed a thousand strong elves and they joined the war of wrath. During the final battles Agfaroth leads the attack and is slain by one of the Commander Balrogs.

Year  587 of the 1st age , the war of wrath ends, Morgoth is defeated. Turthoron once again, few in numbers.  Agthallion Aglarmaethor becomes Tur.

​Finding refuge in Eregion Turthoron find peace for over a 1000 years, before Eregion is destroyed and they move to Rivendelle invited by Lord Elrond.

In the Year 3430 of the 2nd age Turthoron join the last alliance, year 3434 of the 2nd age, the batte of dagorlad and the siege of Barad-dur, Sauron is defeated.

Turthoron was never reformed after that battle, too many died.

Agthallion now roams the wilderness helping all good folk as he can.
