Cyrawyn was born and raised in Snowbourn. As so many women of Rohan, she learnt to use shield and sword combat to be able to defend herself. While the actual amount of conflicts she has seen has been limited. Snowbourn always remained just out of reach of any significant attacks. This didn't mean that the people from Snowbourn could sit by and do nothing. 

It was thus that, as the smiths from Snowbourn sought new smiths to fill their ranks, they quickly came upon an issue; most men would not be at the forge and make gear, but go out and ride down the enemy. And most women, while good with a blade, were more weavers and often 'lacked a smith's hands', so the smiths never looked for new recruits among the women. However, for Cyra it was different. 

Cyra never was any good at weaving. Any act of tailory resulted more in a spiderweb than a tablecloth. And other girls often tended to mock her for her ‘brutish hands’. However, one day in her late teens, she decided to look at a smith at work. The smith obviously thinking she was checking him out, was however mistaken. Her eyes were on the work, the blade, the tools. The smiths eventually catched on, but shaked their heads. One elderly smith however did give her a quick basic lesson and try out. Her first smithed object was a spearhead. It was already primarily done, so it was not a piece she worked on completely. However, the elderly smith was impressed. Not impressed by the quality of the spearhead, which was abysmal. But impressed by her movement and force. It made the Smith realise that Cyra had a great potential to be a Smith. But for now, it was common for women not to be Smiths. 

But during the war that all changed. And eventually Cyra was requested to become a Smith. She took lessons for other smiths. And many still didn’t expect much or even just looked on with expectations of a young woman making a fool of herself. However, their smirks eventually dropped when in just a short time, Cyra went from smithing crude hammerheads, to glistering shining swords, and taking great joy in her work.

As time went on and Cyra’s skill grew, an envoy from Edoras noticed her skill and hired her. This was her first time she moved out of Snowbourn and in Edoras she started working as one of the main smiths for the Eorlingas. However, when Théoden King rode out to Helms Deep and Éowyn led the people from Edoras to Dunhallow, Cyra requested leave to ‘see upon her folk’. Which was granted by Éowyn. It was from here she started traveling around, and learning crafting styles and techniques from all over the world, with exception of secretive and lost ones.
She now became a wandering Smith.
