For this D&D campaign, I'm playing a tiefling who's mother tongue is Infernal. Since this is a totally homebrew world, ie my DM made up Literally Everything, I was given free reign to create tiefling culture which I EAGERLY capitalized on. My worldbuilding now. The following links are for the various bits and pieces I've put together about the language Infernal, and the culture of Tieflings. Enjoy!
