They come from Africa. Arid is fine for Regius although they breed in the Monsoon season when the rains bring the grasses which bring the rodents.
Only worry about humidity if there are shedding problems.
A big water bowl, a moist hide for shedding, and cages with restricted air circulation is the usual way to elevate RH.. ie Rubbermaid type rack systems rather than open(screened) top aquariums, where vapor is allowed to escape straight up.
