ANCIENTS:
Hiraga:
Being that nature and water are spheres intertwined and overlapping in many ways, so too are Hiraga and Shoshar. Of all the ancients, Hiraga is perhaps the only one who can placate Shoshar with a stern word. Hiraga holds some kind of control over Shoshar that keeps him from acting against her. The exact nature of this control is yet another secret that Shoshar keeps to himself, but it has halted Shoshar's retribution on many occasions. Shoshar's reaction to Hiraga's presence and influence appears to be begrudging, bound by an agreement signed ages ago.
Danives: (If Vilhelm changes his mind)
As the depths of the ocean are a realm steeped in shadows, Danives is sometimes seen slinking through in the presence of Shoshar, shaping various creatures without permission. The shadow god's tricks and games rapidly grate on Shoshar's patience, no doubt providing Danives with no end to fun. After at least a century of being the butt of Danives' jokes for the sake of goading a reaction, Shoshar has taken to the habit of merely grumbling and trying to ignore the ancient.
Voana:
Shoshar and Voana have the same understanding as any general and the sea. Shoshar's realm is often used as a platform to defend and attack, but it is not a territory that can be held. She has not been miserly in her offerings to him for permission for safe passage on ships, and has thus not invoked his wrath. Such is the extent of Shoshar's interests in mortal conflicts.
Sohena:
Sohena and Shoshar have barely even been introduced. Her presence always garners anxiety in Shoshar, her natural serenity unnerving. No doubt Sohena herself is not the kind to socialise with a wrathful god of water.
Agimar:
Agimar was responsible for manipulating Shoshar to unwittingly carry out his agenda on a couple of occasions. Shoshar himself is uninterested in his work and tends not to socialise with him. Agimar himself has never directly offended Shoshar, as his scheming was never revealed where Shoshar was involved.
Yakushi:
If there was ever a more annoying, relentless, and never ending torment for Shoshar's patience, it is the incessant inquiries of Yakushi. Being proud of his realm, Shoshar initially satisfied much of Yakushi's curiosity about the oceans, wary to keep important secrets to himself. Unfortunately, her hunger for knowledge was insatiable and Shoshar began to cast her away in impatience. Yakushi's questions did not stop, however. She kept coming back and attempting to pick Shoshar's brains further. Thankfully her mercurial attention cuts her questions short after a while. Despite the annoyance of her presence, Shoshar secretly regards Yakushi with an odd fondness, perhaps for relieving his loneliness at times. It is probably why he does not feel justified in attacking her for her insolence.
Neveras:
Shoshar and Neveras are not on good terms. In protection of mortals during various conflicts, Shoshar and Neveras did battle in an attempt to turn Shoshar's wrath aside. Neveras generally won, making their relationship adversarial. Shoshar had a say in detaining Neveras during the War in Heaven, but at a point during the following years, knowledge of the seal enchantment was taken from him by Hiraga under circumstances that Shoshar, again, keeps a secret.
Myra:
Shoshar is jealous of the joy spread by Myra's open and warm heart. This makes interactions with her curt on Shoshar's part. Shoshar can barely stand her presence.
Vyra:
While Myra would barely have the opportunity to interact with Shoshar due to his view of her, Vyra, her twin, actively seeks Shoshar out when it suits her to have an the Water Dragon on his side. Shoshar may or may not be aware of how hollow her interactions with him are, but she is deceitful enough to charm the sea serpent until he is wrapped around her little finger like a ring. In that sense, Shoshar is a victim of Vyra's machinations when others are not there to talk some sense into him.
