He came from a universe that had a large intergalactic civilization of many different kinds of aliens. His home 'planet' was a ball of water, held together by the psychic will of a giant planet-core sized jellyfish. These Jellyfish species, known as the Morau, were scattered accross the galaxy, only coming together rarely to breed every few million years. They have developed a symbiotic relationship with the Frenei species, whom act as their guardians and contacts with the wider galaxy, while also joining with them in the great dreamscapes of the endless sea.

Pre-infinitas, Tamarin grew up in one of the endless seas as a Frenei eel. Frenei had three genders: white liners (either sex), blue liners (female) and red liners (male). As a white liner, he had several pouches which allowed him to store eggs from blue liners and raise them as his own, preserving them through times of rarity and nurturing them to hatch in times of plenty.

The world, known as Ahast, was a place where not just Frenei congregated but many other species as well, as it was a local interstellar travel hub. At the age of 17 he started his own space-shipping business, which was initially successful. OVer the next couple of decades increasing competition from Coreward AIs caused him to spend more and more of his time within the dreamscape and tending to the business to ensure staying afloat. During this time he met with Annastasia and the two dated and became close for a little while.

EVentually they parted ways until a couple decades later, when Annastasia had asked for Tamarin to carry her eggs temporarily while she went on a freight trip. Unfortunately the freighter exploded due to a navigation error and collision, supposedly killing her. It was around this time that he decided to close his business and tend to her children in her absence. He was migranted from here to infinitas.

Tamarin's history on Infinitas is a long and complicated one, featuring many adventures and associations with varying characters. He spent most of his time in Marsillion initially, then moving to it's outskirts to a home near the water front. The dozen eggs he had brought with him eventually hatched and his family grew. There were a few discoveries and inner revelations about the Jellyfish Marau, but they proved to be unsubstantiated, instead discovered to be the works of parasites. Another interesting development was finding Annastasia: frozen in ice for almost a hundred years, in a perpetual dream state as she had been migranted off the ship into an alternative universe.

She joined the family in a new body after rescue, the happy reunion allowing for a great deal of expansion of their efforts nad assets. With her guidance, Tamarin established a counselling business first in Marsillion, then after many months decided to move to Arcford. Goodbyes were said and the entire family unit moved to Arcford.

After the departure of Marsillion, a rapid pattern began to emerge in Arcford where those with deep connections to the town were being migranted or breached out to it, following the town in essence. Though things on the island were stable after the initial turmoil of the town disappearing, the family made plans in case they were separated, especially as they each had varying levels of attachment to the town.

Almost a full four months after the departure of Marsillion, he was brought in via a red breach to the new infinitas.
