Jel is the native language of the Argonians(Saxhleel) is spoken in a variety of sounds only documented to be understood by other Argonians. There is not enough known information in the Lore to be able to formulate it in written documentation.
3E38, 2nd of the Second Seed, 1:15am
Seven old, fierce, and alien looking Argonians surround a single egg. They watch silently as the small shape from within starts to move. Finally the eldest of the Argonians spoke in the tounge of Jel.
From his throat emanates a number of croaks and squeaks then the others make a scratchy grunt of recognition.
They work together to bring the egg to a deep pool whose base is made of a living Hist's roots. The liquid within is the Hist sap. Indescribable in color and viscosity for it is constantly changing. They set the egg in careful not to break it before it is ready. The shape within starts to change as the egg rolls into the pool and disappears into the liquid. The elders wait for six and a half minutes until a shape slowly starts to rise from the depths. The hatchling breaks through to the surface and wakes the elders from the trance-like state of being close to the Hist. Black and Red in color with large, scaly, ears and round green eyes he swims to the edge of the pool and is lifted by the eldest Argonian and wrapped in a blanket. The elder looked at the sky having foolishly forgotten it was the Season of the Shadow. He looked at the other elders.
He puffed his cheeks and made a contingent of grunts, croaks, and squeaks. He was ordering them to prepare to teleport him to Archon.
The elders were very powerful, old, and wise Argonians. They knew better than to deny Black Marsh a Shadowscale. As the eldest was enveloped in a purple haze of magic he was transported through a complex of spectrums and radiant light that dispersed as his toes touched ground on a poorly paved, decrepit, brick street. Holding the child firmly he set off down the road towards a large cluster of old houses, rotting shacks, and dark alleyways. He then turned down an alleyway where two Argonians stood in dark sets of armor. He came to a small courtyard heavily shaded by the layers of houses and shacks. The sky was somewhat visible through the thick canopy of trees that surrounded Archon. He approached a door and knocked. The door opened with a loud creak and he was met by a Kajiit with dark-brown fur and a pure white tail.
