Pipiyu's family is of Uldah's upper class, the noble Lala house having made their gold through a long history in textiles and vocality in politics. Only recently in her lineage has religion been taken up occupationally, though worship of The Trader has been ever-present.

Textiles were highly profitable, however, work in Uldah's temples proved more so - and, near-guaranteed a resting place in the Ossuary's deepest depths, often reserved for only the most virtuous and moneyed. Pipiyu's whole life has been entirely devoted to Nald'thal and his order. She is quite adamant about one day laying at the bottom of the Ossuary herself, and often cuts much of her earnings in offering to the deific twins and their temples.

Before the Calamity Pipiyu worked between both the Arrzaneth Ossuary and the Milvaneth Sacrarium; imparting wisdom and support to followers, filling Alms boxes, passing on the knowledge of the arcane -- and, in the case of being situated in the second of the temples, she would busy herself often by providing treatment and encouragement to the sick or injured, while at the first location she would ensure safe passage into the realm of the dead (you know, for when treatment at the wards didn't go as planned).

As the Sacrarium underwent its repair Piyu found herself situated more frequently within the Ossuary than in Uldah's temporary wards. This increased amount of time beyond temple walls drew her attention particularly towards the ill-treatment of Uldah's refugees and lower classes, towards what corruption manifests within even the Syndicate and their brass blades.

Pipiyu hopes to see that true peace, order, and power is restored to Ul'dah. Motivated by this, she left the temples to gather and grow a band of friends, establishing (likely to Nald'thal's approval still) a business; Sundries of Sand, a stop for adventurers on their way through or from the Goblet. The business was legitimate, hough for a cycle it served as a front to the group's vigilante heroism, which was kept a secret from public eye until Kukuro, Pipiyu's husband, retired from his position as one of Ul'dah's Lieutenants. This enabled the group to formally and publicly establish themselves as a Free Company, which the Sentinels of Sand are now recognized as.
