Shikudo
The Sentaari staff style was once practised by the Sentaari monks and was used in conjunction with their Kaido and Telepathy skills. Utilising edgeless weapons, the art form allowed the practitioner to defend themselves as well as strike back against attackers. While several variants existed, the only surviving refrence was of the Grove of Winds variant that the Princess Catarin deSangre used to fight Lord Odysseus Rani with during the Tournament of Blades.
The records of the fight between the Princess and the ex-Knight included detailed descriptions of her various forms, from the highly defensive Tykonos form, to the more offensive Willows Shaken by the Wind and Willows in Rain Storm forms.
During that same period, Castomira Brangwin brought about the slow demise of the fighting style. When her Royal Elites stripped the monks of Judgement Mountain of their weapons, the Grandmaster of Flowers meditated for a month upon the dilemma, coming up with the solution in the form of Tekura. The weaponless fighting style freed the monks of the hindrance they were faced with and gradually replaced and phased out the former weapons based variants.
