Mayhap, naught and out of place poetic dialogue

[Kazrah]

You can still talk old english and not overuse words, and old english can be spoken casually without having that poetic feel to it. I don't want it to be modern either

Technically it goes somewhere between Middle English and Shakespearian/Elizabethan era English.

Old English is much closer to Welsh, because apparently it wasn't until Chaucer that vowels were invented in the English language.
