Estriis's Links
According to Tesei he is considered Gemini's grandparent, and he's not that thrilled about it. While in the past he didn't really have any hash opinions on the Skarrid, he found it weird that they decided to split into two people. And frankly it makes him a little concerned that he will split into two when he dies, since he looks fairly similar to Casix.
After dropping the twins off for Tesei to raise, he did grow attached to the two and would treat them as his own flesh and blood. At the same time he likes to poke fun at them, especially when they were little. He seemed to be quite happy about playing along with tea parties, although one might argue that giving a child boiling water might be a bad idea.
Despite being created by A'vock, Estriis' relationship with the god is little deeper than a business relation. He remembers the death of Ankarresh and sister Aquarius very well, and holds A'vock personally responsible for their deaths.
He wants nothing to do with the god.
Tesei is one of the few people Estriis has a deep respect for. Actively seeking to keep them save and going out of his way to preserve the essence of his favorite Skarrid. Tesei is the only Skarrid Estriis has actually decided to help with retaining their memories, and will likely be the only one who he'd do it for. The two have a relationship similarly to siblings, thick as thieves. While at the same time they can take jabs at one another that might come off as hate-filled, but rarely are. He genuinely holds a love for the Skarrid in his old heart and still does, but at the same time he still occasionally babies her like he did a long time ago.
Tesei likes to fondly say they have an army of parents and siblings: the ones they were born to, the celestials : Ankarresh and A'vock, the Skarrid. And Estriis, who's always been a bit of both. A father not by blood or upbringing, but certainly by guidance and care, and the type of sibling that your best friend is - the one you've experienced everything with, from devastating fights to unforgettable acts of affection. Their relationship is an odd, tumultuous but steel-strong one. Three thousand years will do that to ya...
Sure, between being called Virgo or Denna one too many times and Estriis' dramaticism, Tesei finds the skarrid an absolute handful. They know each other so well they're one of the only people that know how to run each other's patience dry. They can scope out each other's buttons and relentlessly jab at them. But then have a laugh about it after. And Tesei wouldn't have it any other way.
They may call him old man with a smile and try to get him out the house and travelling, lest he 'turn into a gargoyle', but they love him dearly and have looked up to him for the last 3 milleniums, always maintaining the hope that they've filled the hole in his heart that his child, Denna, left.
