Saria is an alternative name of Mount Hermon (which can also be pronounced as Sirion), as attested in the Epic of Gilgamesh. This is referenced by the namesake Operator's silver hairs, which refers to a nickname for Mount Hermon, "the gray-haired mountain."
Saria's Calcification and calcium-based abilities may allude to Mount Hermon being primarily composed of limestone, or calcium carbonate.
Despite Saria carrying a jet injector, she attacks her enemies in melee range by bashing them with her shield.
Saria was originally intended to have a ranged attack (similar to Liskarm), but this was changed during Arknights' development.
The amount of healing that is noted in the description of Calcification is applied each second of its duration, instead of being applied just once. This per second application is not visible in the description.
Saria is the only 6★Defender whose attack range is only on the same tile as her.
She's also the only melee Rhine Lab affiliated operator, compared to the rest of them who are Ranged operators.
