Time sensitivity

Time sensitives were individuals or species that were sensitive to the ebb and flow of time. Tharils were one such species and were highly prized by humans as they could navigate the time lines. Dwarf star alloy was the only substance that could hold time sensitives like Tharils. (DW: Warriors' Gate)

Time sensitives could also manifest amongst human populations. (BNA: Walking to Babylon, EDA: Camera Obscura)

Another species which was time sensitive was the one Eve belonged to. As they were time sensitive, they were deemed a threat and were exterminated during the Last Great Time War. Eve was the only survivor. (SJA: The Mad Woman in the Attic)
