Grillern âGrillbyâ Phaze
Grillby was âbornâ just a few years before the barrier, and due to circumstances of the war ended up both an orphan and artificially accelerated halfway through his childhood by the time he was sealed behind the barrier with his siblings.  In that time heâs fallen in love (it confused him), been soulbonded (which also confused him), and ended up heartbroken, severing the bond - then raising his former bondâs children himself a decade later.
Yeah, heâs pretty emotionally and mentally screwed up.
But on the Surface, he not only has a new and bigger bar (with additional staff), heâs got three Partners to help him sort out his head and soul. Between them and his open policy for any customer that doesnât make trouble, his bar has become a hopping hotspot for the local queer community. Heâs taken to wearing an Ace pin on his vest to cut down on the amount of blatant flirting directed at him.
Brigitte is a pre-war fire elemental, one of a not-so-powerful line, but a sociable one. Well-socialized, she risks living in the Echo Marsh of her Underground, patrolling daily simply for the thrill of it and love of the people. While she was the only elemental to safely make it into this Underground, sheâs far from the only elemental there now - sheâs had two Grand Summers, and happily counting down the months to her next on the Surface now.
In the meantime, she mothers  the new Risen still happening in the Marsh, making daily visits down to check for new ones before returning to the Surface to help take care of the ones already there. As a side business she brews and ships various artisan alcohols, catering more to the whiskey and rum lovers in the area - and flirting with Comic âSansâ Aster, who runs the bar that sells the largest portion of her booze.
Visually sheâs cultivated having very ample curves to go with her feminine-presenting preferences, and is a light purple flame with yellow-to-white edges.
Grannus âGrillbyâ Inferi
This ice-blue flame is something considered almost an abomination by pre-war elemental standards - heâs a hybrid offspring of a Fire elemental and a Boss ice monster. Results? A very untypical Grand Elemental with an incredibly high resistance to water and ice. Even as a small child this flame was incredibly dangerous.
Considering his infamy, none were surprised when out of boredom he opened a bar in the coldest, wettest part of the Underground, saying it made for better atmosphere. At the very least it made for better chances to get in fights. But as the only local place to get hot food and drinks at any time, he kept his clientele.
And then Jack and Jillaine set out to seduce him, and Grannus discovered an all new side to his fascination with pain.  With the volatile elemental âcollaredâ and in a stable relationship, heâs got an outlet for his urge for violence and pain - as well as the children he wanted but thought were impossible due to his mixed lineage.
(On the surface, heâs running a Dungeon that caters to both humans and Monsters)
When your home is perpetually cold, if not outright freezing most of the year, being made of fire becomes a very important blessing. Ogon is the head of a small family of fire elementals, generally regarded as the most Essential Treasure of their Underground. This constant respect has resulted in a very strange development in their personalties.
Ogon is not particularly attached to any one interpretation of gender, and delights in dressing up however she wants - wearing whatever ornaments and baubles they wish. He will wear as much, or as little as they want as she wanders the Underground, dispensing heat and re-stoking the fires that augment the Core made by the Royal Scientist.
With the Barrier gone and the introduction of human technology, Ogon has taken control of the Underground, leading it with a firm hand and an eye towards turning it into a profitable town - they have a pre-built kingdom already mostly protected from the weather. With the greater fuel efficiency available, greater resources . . he can see a future where the mountain becomes a prosperous hub of progress.
