Fire magic. Girshu smelled it, and had to control himself from turning around and sending a spike of ice into the pyromancer's skull. He shouldn't do that, he most definately shouldn't. Killing humans in a human city always caused so much fuss. And he had been warming these damnable beers all night now, in exchange for lodging and a meal. If he were to cause a ruckus like that, the barman would throw him out and all his efford would've been in vain. It was just some simple pyromancy after all, a small flame summoned by one of these chaotic mages who didn't have the discipline for the much better and more controlled frost arts. Humans, they were like children. Annoying brats, that is.
Girshu wrapped his hands around another one of the beer mugs. It wasn't actually frost magic he was using, he wouldn't waste his magic on such a lowly task. No, it was a simple biological feature combined with thermodynamics. His blood was -40 degrees celsius, and even his skin was around -20. He just needed to touch the glasses until they cooled to roughly 0-5 degrees and they'd be cold to these people.
A few minutes later though, it seemed like the self-control he had imposed upon himself to deal with the pyromancer was in vain. The barkeeper approached Girshu and brought the man along, claiming that the beer had suddenly turned warm again. Girshu wanted to scold the fool, the barkeeper thought that his cooled beer couldn't heat up for some reason, rather than comprehending that people drank the cold beer too quickly for it to get luke-warm again. No, such permanently cold beer would be indefinately more expensive, lined with nevermelting ice or served in blue ice mugs.
But his real loathing was aimed at the elf who was challenging him, the elf and his fire magic. Girshu could smell the sulfur on this man's skin. Very subtle, inperceivably faint to humans and even elves, but Girshu could smell from the man's hands that pyromancy was not alien to him. Yes, his kind could distinct these terrible madmen from their already chaotic kind from smell alone, and normally the elf would've already been dead by his feet for it. But now, but here, that was not an option. Too many people, too many heroes.
So, as the elf introduced himself as "Gimli" and pretended that he didn't know exactly why his beer had grown lukewarm, Girshu sized the elf up and grabbed the beer that the barkeeper was holding. He wrapped his hands around it and made it cool again. A small fire burned underneath the cup, the heat intense enough that even a normal person would notice the agonising sensation, but Girshu pretended not to notice. You know, even if the light and noise that the fire produced wouldn't have tipped anyone off. The elf was testing his patience, testing it really hard. But he was keeping it hidden just a bit too well, just enough to make Girshu look like the bad guy if he were to rip this man's throat out.
As the glass started to crack from the intense difference between hot and cold, Girshu placed the mug on the bar before it would shatter and cut his hands. Grabbing the barman's collar and pulling him closer, he whispered to the man that this elf was a pyromancer and that he best resolve the issue or evacuate the bar. Because if he wouldn't do the former, Girshu would make sure that everyone would strive for the latter. The man grew almost as pale as Girshu and nodded, quickly walking away.
The barman soon returned with a new mug of ale for Girshu to cool. It didn't seem like this Gimli fellow was continuing the sherade though, not surprising considering the impulsive nature of these pyromancers. Instead, he held up his hand and openly showed a fireball hovering inside it. Girshu had to control himself once again upon seeing the man so carelessly using his fire magic, his aura of cold grew more frigid and the hatred was clear on his face, but then he had an idea. A wolfish grin appeared on his face, his long teeth exposed as if he were a demon wolf pretending to be nice, and then imitated the laughter-thing that humans did to show amusement. If this pyromancer was so impulsive, he probably wouldn't even question Girshu's quick turnaround.
Girshu's expectations were correct, as the elf didn't seem suspicious at all when he asked for his name. Girshu gave his, and then asked the bartender to bring Gimli a cold beer to replace the one that his fire magic must've accidentally heated up. Girshu would make sure it was extra cold this time, so it wouldn't happen again.
Yes, extra cold. As Girshu wrapped his hands around the ale this time, he used his cryomancy. Small snowflakes started to form inside the liquid, too small to see unless you held the glass really close, but they were most definately there. Oh yes, Gimli would notice them, he would be well aware of them when he took his first sip. These razor snowflakes with their hardened sharp edges wouldn't just cut into his skin like usual when people touch or walk through it, no sir. When someone would drink it, a thousand little cuts would shed open their throat and the victim would literally drown in their own blood as their lungs would fill up. An extremely messy, painful and satisfying death. Well, satisfying for Girshu.
Girshu continues to smile his big tooty grin and slides the ale to his new bestest friend Gimli. Taking his own beer, he held it up for them to take the first big sip together.
Cheerss.
