Orshogoth Reho Lagonathnu is the sire of Rehonu Orshogoth and the biological offpsring of Vasonu Orshogoth.

He was the last Urnati Silver Dragon to be born before the Cataclysm, and as such, was much younger than his sire and was more affected by the DNA changes. The changes also began to manifest in him as he aged, including gaining the ability to communicate telepathically with others of his bloodline.

Lagonathnu kept the dragons from perishing during the 30-Year-Winter, finding food sources and places to rest and breed. His name is spoken by other dragons in a reverential tone. Those who malign him do so at their peril.
