Refs in Obscura most commonly exist in character as beings known as "Keepers". The existence of Keepers is not known in-universe at the start of the campaign. Keepers can be recognised by distinctive off-white robes.
Keepers understand magic and science intuitively, but are bad at talking about the subject in an abstract sense, so you can ask them “how could I do this?” or "could this work?" and probably get an answer, but if you try to engage them in a general discussion of metaphysics they’ll probably have trouble giving you any insight you don’t already have.
Keepers can't make or receive calls in character. If a Keeper makes a call, it will be to deliver an effect from another source, such as an environmental effect or ritual fallout. Hopefully the source will be clear from context, otherwise you can ask for clarification.
Keepers can be targeted by rituals and experiments, but can't be affected by such things, however you may be able to gain information from experiments and divination on Keepers.
Keepers can't knowingly lie or mislead, and won't deliberately tell any of your secrets to other players or NPCs. You should feel as confident having a conversation in character with a Keeper as you would out of character with a ref. Note though that a conversation you have with a Keeper can be overheard by others in character.
