Oh, it can fit in Legend,. But it doesn't really fit with other characters I'm familiar with, and probably not this game.
Here's how it came to be: Friend got bored, used some meme generation to grant other friends their D&D Name, Race, and Class based on a d20 roll and First Pet's name (arbitrary details). I rolled a natural 20, he gave me:
CRITICAL
Your name is HUMAN
Your race is ELF
Your class is DWARF
STR 18 DEX 5 CON 13 INT 17 WIS 10 CHA 3
Thus was born Human, the Elf Dwarf.
I responded and decided that this is his backstory, generally speaking: Human was so utterly horrible at being an elf that he went to go train with the dwarves, and just ate, slept and drank the dwarf lifestyle. He studied everything about being a dwarf, trained to be brawny like a dwarf (which is seriously hard for an elf, guys), and drank so hard he made an ass of himself stumbling over his feet and words, and so he alienated himself with just about everyone. This explains his stats and is a perfectly viable character why not.
