Searched but couldn't find a thread I believe I read here.

With projecting wizzers and astral enities, would you say/judge that they needed to know the same language?

With all attendant rules of understanding each other.

Now a spirit to shamen summoner may just use the prefered language of the summoner. But then a River free spirit may use images and sensations to communicate. Two Astral wizzers, constrained by how they think, may need a common language. Or perhapes they could 'speak' empathically?

Personally I use all three for flavour but I'd like to know if there's an official take.

If the two astral beings have the same language in common they can use that to communicate.

If the two astral beings do not have the same language I see no reason why an assensing test at the 5+ would not allow accurate communication with astral emotes.

Whats the take on Free spirits that dont often have a listed language?
