Was donking around on Tv Tropes when I came across the description of a fic that instantly piqued my interest. Unfortunately there was no link to the story at all and I would very much love to read it. I copied the description of it hoping someone might recognize it and give me a link. I'd really appreciate it.

One furry fanfic had a furry convention (as in the entire hotel and some of the surroundings) transported to a magical universe that's a fairly standard (albeit furry) low level magical verse. They quickly prove highly innovative to the point of learning how to use the magical mirror that brought them there in ways they never thought of and set up a mercenary company using military weapons scavenged from dead alternate earths (they destroy a gigantic nearly indestructible magical scorpion creature within minutes to the complete shock of the locals, something that normally would last for months before dying of starvation after destroying everything it could in the meantime).
