Around 1000 AE documents record a King Allarch reigned during some of the time up until 1048 AE, if not the entire time.
One obscure document found claims that Allarch and his entire family were killed during an Empire raid on the capital, however, this is not supported by any other records and there are certainly no records of the Hadovians having capacity to breach Geldheim defences – the idea is frankly preposterous. Suffice to say, Allarch died, and it does not appear he left heirs.
