Gawyn Harowcal
From BHH Wiki
Gawyn Harowcal was a loremaster, an expert on dragons and the 116th Ramaloce Heru, one of the Four Great Mages, and Tom's key character in Maisraln. He grew up on Lonaoiisil, training as a loremaster, and at some point became the Ramaloce Heru-in-Waiting.
In 1620 KY, the incumbent Ramaloce Heru died suddenly alongside the other Four Great Mages, and Gawyn learnt from Elvar Murchaidh that he was now the Ramaloce Heru and that he was now the Hermadiúir. He then travelled with Elvar to meet their other new comrades, Lyra Felise and the Ashen Darkside.
