Prior to Raboniel's occupation of Urithiru, a team of Navani Kholin's scholars led by Brother Benneh was using a Thaylen vacuum tube from the institute as part of weather observations on the Cloudwalk. Initial readings from those observations indicated that atmospheric pressure and temperature on the Cloudwalk increased ahead of a highstorm and that the temperature on the Cloudwalk is generally several degrees warmer than the temperature on the plateaus at the base of the tower city; these discrepancies from what would ordinarily be expected are the result of the Sibling being able to produce just enough Towerlight to power some of the tower's most basic fabrials.
During the occupation, as part of her attempts to produce anti-Voidlight, Navani requested the institute's vacuum tube be moved from the Cloudwalk to her lab, a request which Raboniel granted, though she found it strange. The tube ultimately played a critical role in the creation of anti-Voidlight, allowing Navani to isolate Voidlight from Odium's pure tone so that she could then use his opposite tone to convert it to anti-Voidlight.
