The Umaeda clan has a unique power that has run in the bloodline of the clan lords since one generation after the Inception, the 2nd through 4th generations had the unique power of becoming partially what they strived to slay... Demons. However, during that time a western Knight, Valtaer Naerem was an unwilling subject to an obviously severely outlawed experiment that was some form of culmination of Magic and Alchemy... by using the life essence of a dragon you could theoretically give the ability to shape shift even partially into something resembling they essences former shape (More on this when I actually finish Valtaer). Valtaer, had no place to go when the Umaeda clan, shapeshifters themselves offered him a haven. after being in the clan long enough he obviously had children and so on and so forth. Basically Damira, an 18th generation Umaeda is decended from him. It seems that while most if not almost all retain their demon shift, but a few all decended from Valtaer replaced their demon shift with the ability to become partially draconic, though what dragon lineage they possess at birth is seemingly random. Damira, daughter of Ryuukou discovered upon her first shift that she is of one of several blue lineages. She can manifest slight control over the domain of water and infuse that power into her attacks. She ventures to Ebonmar as a liason between her clan and the Half-Dragon lord Navaros and also takes notably too long to return from her trips there, so it is assumed that she visits friends that she has made there.
