This Sirabre approached the Verdent Hearth offering knowledge of how to infuse plants with necromantic energy. During the course of getting to know the shardbound, The Sirabre introduced herself as 'The Lingering Will of the Ustradi Range', and shared that she has been in the Ustradi Rivervalley before the Mana Wastes were created, making them several thousands of years old, on a similar timeline with Wizard King's Geb and Nex.
To those who have garnered her respect, she will share that they were once a druid who went by the name Kibibi, but took on the the ritual known as Welcome the Blighted Soul, becoming a siabrae, tying her eternal fate to the Ustradi and Manawastes and its corruption and illnesses.
She often goes by 'The Will' as a nickname, and has two weepshards jutting out of her skull, with tattered robes that astute perception or lores of ancient cultures might recognize as Ancient Osirani Druid Priestess Robes.
