Our party is currently playing through Waterdeep: Dragon Heist (no spoilers, please!) and we're nearing the end of the campaign. The other night our party was discussing a teaching exchange of languages, and our party cleric (a human) mentioned that she could teach someone "luraic".
After a few minutes, we all came to the realisation that none of us had a clue what luraic is, or where it came from. It's on her character sheet, and it was picked when she originally selected the linguist feat. Another player remembers her picking it, and recognised the name, but couldn't recall where it came from.
We've since scoured language lists online but can't find any trace of this mystery language. We do know that at some point she transcribed her player sheet onto a new copy to make it neater, so one theory is that her handwriting was a bit sketchy and she copied something incorrectly, but none of us can find any languages that even read similarly to "luraic".
Is this a real D&D language? Does anyone have any theories as to what it might have been before a copying error? Any tips on how to handle this? For now she's removed it from her languages list and is considering alternatives that won't require any retcons.
