Stronmaus, the Storm Lord

Storm Giant Stormguard by Marlon Ruiz

Stronmaus is the god of sun, sky, weather, seas, and joy. He is known by many titles, the most famous among them being the Storm Lord. Stronmaus has a very jovial personality and takes great joy in interacting with his worshipers, primarily composed of storm and cloud giants, especially those that have impressed him. He is particularly fond of individuals who slay dragons and will often offer to reward them should they come near one of his shrines, regardless of whether or not they worship him or are even aware of his existence.
He has led the giant pantheon ever since the disappearance of his father, Annam All-Father. Despite his role as "leader", Stronmaus remains a carefree spirit more concerned with having a good time and encouraging mortals to get out there and slay some dragons. Most notably, he is the patron deity of the cleric Marshall, who is currently waging a war against Tiamat in Stronmaus name.

History

Quest for the Quintus Gems Campaign

One of Stronmaus' shrines sat atop Mt. Kaneshiro, the tallest of the few mountains in the nation of Jezero. It was overseen by Magnus, a storm giant keeper who kept watch over both Stronmaus' shrine and a temple protecting the Green Quintus Gem further down the mountain. Dunames theft of the Green Gem did not go unnoticed by Magnus, who summoned lightning to his hand and threw bolts at the fleeing devil that caused her to drop the Gem. She did not take this lying down and later returned with a host of yugoloth mercenaries, slaughtering Magnus for his interference and leaving Stronmaus' bloodstained shrine unattended.
Stronmaus became aware when the cleric Marshall found the lost relic Grabthar's Hammer and subsequently the Yellow Quintus Gem that went with it due to the artifacts' power over thunder and lightning. Not long after, Marshall had a falling out with his goddess, Waukeen, as his party made their way back towards the town at the base of Mt. Kaneshiro. The villagers told the adventurers of a disturbance up the mountain and they went to investigate the temple where they had previously visited for the Green Quintus Gem. Their search took them further up the mountain then they had gone previously, ultimately ending at Stronmaus' shrine near the summit.
Sized for giants, the shrine was difficult for the humanoids to navigate but Marshall nonetheless was able to climb onto the altar, hoping to get a better look around from up there. In that moment, he was enveloped in light and found himself floating high up in the sky in the presence of Stronmaus. The Storm Lord introduced himself and loudly declared he was impressed that one so small had managed to fell a grown blue dragon through clever guile. He offered to empower Marshall now that Waukeen had abandoned the dwarf, promising him great glory in dragon slaying. In awe at the god before him, Marshall eagerly accepted.
Stronmaus kept an eye on Marshall for the remainder of his journey in Jezero. He even answered Marshall's call for aid at the beginning of a great battle directly, temporarily transforming Marshall into a storm giant while Marshall's companions took the forms of lesser dragons to battle the powerful ancient red dragon, Yoltoorshul.
After Marshall and his companions stopped the Blood War from spilling into Nexus, he began to travel the lands and spread the word of Stronmaus to any who hadn't heard it. While traveling, he was tracked down by Lady Kemlar who claimed she wished to meet one of the Heroes of Jezero. She listened attentively to his praising of Stronmaus and made a seemingly joking suggestion that if Marshall really wanted to show his love of Stronmaus, he'd march an army of giants into Avernus and slay Tiamat in Stronmaus' name. Marshall decided that sounded like an excellent idea. He traveled the world using his status as a high priest of Stronmaus to rally giants to his cause (and slay many dragons along the way) before opening a portal to Avernus and beginning a long siege against Tiamat that rages of this day.

Shadows Unleashed Campaign

While exploring the Giantsheel Mountains, the Headhunters came across a shrine to Stronmaus near a mountain peak. Chigiri recognized the shrine as belonging to Stronmaus, having read about the Storm Lord in an ancient theology book. Having found some ancient dragon bones on the way up, Kiri put the bones upon the altar and Stronmaus, amused at the offering, sent him a bag of holding and told him to slay a dragon himself if he wanted a real reward.
Some time later, the group returned to the shrine after Chigiri had slain the green dragon Feyrbrand. Placing Feyrbrand's bones upon the altar, Stronmaus accepted his worthy offering and rewarded the ninja with one of the two Lightning Kopeshes. Rewarded with one of the fabled Seven Swords he'd long been seeking, Chigiri praised Stronmaus as his new lord and began to pray to the Storm Lord regularly. He would often call Stronmaus' name when striking enemies with his Lightning Kopesh, though he'd sometimes praise Stronmaus even when using other weapons.
Some time later, Gentleman Jack heard the story of how Chigiri had obtained his Lightning Kopesh from Pryce. Having found an old scroll in the library that depicted the Kopesh as a one of a pair, he robbed a museum for some dragon bones and took them up to Stronmaus' shrine. Though Jack had not slain a dragon himself as Stronmaus would have preferred, he nonetheless delivered the second Lightning Kopesh knowing that Jack intended to give it to Chigiri.
